In addition, it is not even proper for all projects even the erc20 tokens to be concentrate on one network. Besides the a network congestion, due to many projects inflow, there is no room for competition, and the result is high network traffic, market monopoly, and higher transaction fees. The coming of Binance smart chain is a good development, at least, to ease the Ethereum network congestion and high transaction fees experienced this days. I think that the launching of more Blockchain networks on the crypto ecosystem is good for further crypto development and growth.
