However, I dont know what to expect, but, I am sure we will get BFG token and token collection will be spread within 30days as reward and bonuses from activities

Initially, Betfury said that $20 million was allocated for the Cryptodrop event, and the prize pool consists of cryptocurrencies (not only BFG) that they have accumulated over a certain period. In addition, they even published the
address of this pool, and if you look at its contents, you will notice that there are not only BFG tokens there.
To be more precise, this address has 350 million BFG tokens, 1550 ETH, 35 BTCB, 1 million BSC-USD, and 850k USDC. I assume that these are exactly the cryptocurrencies that users will be able to get in exchange for points.
