1. Is EOS RAM worth investing in?
Recently, the price of EOS RAM has fluctuated greatly. The reason for this is that some people want to use RAM to hype mining.
There are three kinds of resources in the EOS system: CPU, NET and RAM. Among them, RAM is the storage resource of EOS. The EOS system has a built-in RAM trading system, and RAM resources are traded through this system, that is, the acquisition of RAM resources requires It is purchased through EOS, and it is priced through the modified Bancor algorithm. The price has a lot to do with the amount of EOS in the RAM pool.
In the history of the development of EOS RAM, RAM has been hyped once. Some people have earned dozens of times EOS on RAM, while high-level access to RAM has not yet paid back.
Not long after the EOS mainnet was launched, RAM had not yet been issued. Speculators believed that the EOS ecology would inevitably become popular, and the demand for RAM would continue to increase, so the limited amount of RAM would inevitably skyrocket.
We know that RAM is the storage resource of the EOS system. If the price of RAM is unstable, the skyrocketing price will definitely not be conducive to the ecological development of EOS. Therefore, after the speculation of RAM, after discussion by the community, a gentle expansion method was finally adopted to stabilize the RAM The price, that is, every time one block is added to the EOS main network, the total amount of RAM will be increased by 1KB, and RAM still adopts this gentle expansion method.
It is precisely because of the mild expansion of RAM that the price of RAM has finally stabilized. Let's take a look at the total amount and usage of RAM through the eospark tool.
According to the statistics of eospark, the current total supply of EOS RAM is 193.34G, which is more than three times that of when the EOS mainnet was first launched, and the allocated RAM is 82.81G, which means that it has been allocated in the RAM pool. For the amount of RAM sold, the allocated RAM accounts for 42.83% of the total, but the actual used RAM is very small, only 11.92G, which means that only 11.92G of RAM is actually put into use, which only accounts for 6.17% of the total amount of RAM, there is still a large amount of RAM that is not actually put into use.
From the data above, we can see that the total amount of RAM is 193.34G, but only 6.17% of it has actually been used, and more than 93% of the RAM has not been actually put into use. Therefore, for the EOS main network, RAM resources are not scarce at all. Judging from the current development status of the EOS ecosystem, the demand for RAM resources will not explode in the near future, so from the perspective of supply and demand, RAM is not worth it. Investment, because there is a lot of spare RAM in the market that has not been used.
Of course, in this wave of RAM speculation, some people did make money. Some friends in the Canon group bought RAM as soon as they got the news of RAM mining, and now they still make money. The time window period of many opportunities is very short. If you don’t rush in at the first time, it’s best not to go in and get involved, otherwise there is a high probability that you will become a taker. If you are engaged in short-term, you must run fast just work.

2. How to do a good job of security for EOS accounts
In the hot DeFi market, some people made money and left, some lost money and left, and some participated in projects and lost coins. The day before yesterday, a user broke out that when participating in the mining of the diamond project, the private key of the account was modified, and the EOS assets inside were transferred away. According to the analysis of TokenPocket, the user’s coin loss this time has nothing to do with the diamond project. After all, the contract code of the diamond has been audited by SlowMist, and the contract account has also set up a multi-signature function.
If the contract code of the diamond project is really tricky, people will not only steal a user's assets, but the project party can take away all the assets in the contract account."Moreover, during the audit of the diamond contract code by SlowMist, the market value of the assets in the contract account has exceeded 100 million, and the account has not yet set up multi-signatures. People can completely transfer the assets in the contract account. After all, the account was still subject to Under the unilateral control of the project party, the project party can unilaterally transfer all the assets in the contract account. Coupled with the anonymity of the team, you will never find anyone if something goes wrong. In such a critical"testing period
None of the diamond project parties ran away, and it is impossible for others to just steal a little bit of your assets.
But in any case, as investors, we still need to be more vigilant. Safety awareness is a must, and preventive work can be done in advance. Let's take the TokenPocket wallet as an example to see what security precautions we can take.
1. Check the authorization status of the EOS account for DAPP"Found in TokenPocket's wallet management interface"Whitelist Details
, click to open and you can see the EOS DAPP authorized by the EOS account.
For DAPPs that are no longer in use, the authorization must be cancelled, and to enter the DAPP through a regular EOS wallet, you must be very cautious when authorizing. When importing the wallet, try to use the Active permission to import.
2. Check the permission settings of the EOS account
Find the permission management in the wallet management interface of TokenPocket, and then click to enter the permission management interface of the account, as shown in the figure below.
Check the permission settings of the account in the permission management interface of the EOS account to see if there are redundant permissions. The EOS account has an Owner and an Active permission by default, and a public key is usually bound by default under these two permissions. In addition to these two permissions, custom permissions can also be set. If you have extra permissions, you must carefully check whether you added them yourself, and whether the private key corresponding to the bound public key is in your own hands. If you find some permissions or public key information that you don’t know the source of, you must Delete it immediately.
In some DAPPs in the early days of EOS, sometimes it is necessary to add some project permissions. If it is not deleted, it is very dangerous, so you must check your EOS account.
According to PeckShield's statistics, up to now, there are more than 3,000 accounts whose account permissions are controlled on the EOS public chain, and the assets involved have reached 18,600 EOS. Therefore, if you often play EOS DAPP, you must check your EOS account to see if the permissions are controlled.
If your EOS account permissions are controlled, the funds may be stolen immediately, or someone may be watching your account balance to catch a big fish. So be sure to check the account permission settings and delete redundant permissions.
3. Regularly replace the EOS account key
For our EOS account, try to change the private key every once in a while, for example, once a month. If your EOS account has not changed the private key for a long time, it is recommended to replace it as much as possible to prevent some possible problems. potential risks.
Of course, after changing the private key, you must take good care of the private key and do a good job in basic account security. For example, copy the private key on paper. If you have to save it online, you must first process the private key before saving it. For example, segments are saved in different places, or characters you are familiar with are inserted in different positions of the private key when saving. In short, the original and complete private key information should not appear on the Internet as much as possible.
4. Consider using EOS cold wallet
When performing operations related to EOS accounts, you can consider using a cold wallet for operations. The cold wallet and the observation wallet need to be operated together, because the cold wallet is not connected to the Internet, and the networked observation wallet is imported with an account or public key , so the private key is relatively safe.
About how to create an EOS cold wallet, I have already written in the previous article, which contains very detailed operation steps, you can check it directly, the link is:https://bihu.com/article/1808014923。

3. In the early morning of this morning, YFC Fish Pond launched a large number of currencies
In the early morning of this morning, many currencies were listed on YFC’s fish pond, such as DICE, MEETONE, TPT, and BG. Now almost all the available currencies in the EOS ecosystem are basically in the YFC fish pond.
Although YFC was not created by the pig brothers of Dafeng Harvest, it still follows the style of pig brothers in some aspects, such as in terms of publicity. Many friends jokingly said that they couldn’t help but laugh when they saw the copywriting of DFS/YFC. They are so talented. For example, before a large number of currencies were listed on the YFC fish pond yesterday, they introduced these currencies in this way.
EOS/SOUL 2 500 Famous games spanning three major public chains
EOS/TKT 1.1 200 famous blockchain games that all bosses love to play
EOS/IQ 1 100 BM has called for orders, and Binance has been listed on its famous blockchain content platform.
EOS/DICE 1 100 An entertainment platform that has surpassed a hundred times on EOS
EOS/HBB 1 50 Bihu community currency operated by Internet celebrity Deng Jiaozhu
EOS/PINK 1 50 A very dreamy community coin
EOS/TPT 1 100 famous wallet platform currency
EOS/WAL 1 100 Famous exchange platform currency
EOS/NDX 1 100 Famous exchange platform currency
EOS/MEETONE 1 100 famous wallet platform currency
EOS/BG 1 100 Leading entertainment platform on EOS
EOS/VIGOR 1 100 BM is the No. 1 DeFi abroad.
EOS/VIG 1 100 BM is the No. 1 DeFi abroad.
EOS/DAPP 1 100 The No. 1 DeFi abroad in my mind.
The listing of these currencies on YFC actually means that Dafengshou can use these currency market makers to earn coins, and then take the LP Token that was made in Dafengshou to YFC for re-mining. Currently, dual mining in the EOS ecosystem is very popular up.
It is precisely because of the continuous tossing of DFS that when the market fell in the past few days, it seemed that the decline of DFS was relatively small.
However, the overall price of EOS DeFi coins has been quite weak recently. Whether it is OGX/BOX or DMD/CRL/YFC, they have fallen a lot recently, especially some newly launched currencies such as DMD. The amount of funds in the warehouse is increasing, but the price of the currency has not risen, mainly because the market has been too weak recently.
