Coinbase announced that its token sale platform will not use a first-come, first-served model, but instead will employ a "bottom-up fill" algorithm. This aims to promote a wider distribution and limit the concentration of assets in the hands of large buyers. This will typically result in a more substantial allocation for participants requesting the smallest amounts, while larger requests are gradually fulfilled until the supply is exhausted. Regarding the application window, token sales on the Coinbase platform will last for a period of time (e.g., one week), and users can submit token applications at any time during the window. After the window closes, the algorithm will determine the final token allocation.
