this whole bitcoin splitting issue reminds me of when ETH and ETC became 2 distinct cryptos. I don't know what to think about the splitting of btc but i could imagine that the bitcoin we know will take a while before it's overthrown by another cryptocurrency. I have high hopes in ETH too, just don't know if they'll beat BTC this year.
ETH won't be beating bitcoin anytime soon. And a splitting already took place before and everything went fine. Bitcoin Cash could not over throw the legacy bitcoin, and I don't think any split will be able to do so. Another split is coming soon around November, though support for 2x is declining. Lets see what happens then.
