Bitlayer, as the opening work of the Binance $5 million series, I have checked in for 7 days. The second week is a bit more challenging and requires more funds. I will still focus on completing the first week. Checking in more than 10 times can earn 100 wbtr tokens. Everyone must persevere and not forget. So far, I have earned 20 Btr tokens, #币安Web3钱包联手撒钱 $BTC .
