I feel that BSC is not necessary, otherwise it is too harsh.

I suggest everyone at least brush 200u of BSC Alpha once during the May Day holiday. Why? Because we need to follow Binance's policy? Binance Alpha will definitely support the BSC chain. What if the next airdrop requires points + purchases of BSC Alpha? Moreover, it seems that as long as you master the techniques for brushing the BSC chain, you can also earn U. I brushed 8 times for 1050u and made 20u. That counts as half an airdrop $BNB
