Will it be something used in more places or is it just for binance ? I mean I don't know what the purpose of binance chain without really making it used in more places? Without using it many other places the chain wouldn't be really useful to us. Look at coins like nano, it says it is instant and amazing and blockchain is super fast but in reality is it used as much as bitcoin ? It is not hence we may not know how fast it would be at the time of bitcoins peak, would it be good enough in that case ?

Ethereum had a trouble only during cryptokitties fever when everything there clogged the ethereum chain but we don't know if binance chain would be really that fast or not without actually testing it at those levels. I hope it would make a change in blockchain world but I doubt it.
