It may be fast but wont really be enough for ERC20 token users or supporters to switch up on Binance chain.It would still be a good alternative though and it wont really cross the borders.
4 ERC20 tokens already switched to Binance chain
Many more coming.. ETH is really way too slow compare to Binance chain 1 sec block
Sorry but I'm not familiar which 4 ERC20 tokens have switched to Binance chain, so it's interesting. I think Binance one advantage though that projects are looking is that it's one of the top exchanges right now, so they have a backing, but this sort of centralized everything in my opinion.
Although four is not a good indication that others may follow though. Ethereum still enjoy the support of the community and projects so it's going to be difficult for them to simply switch.
