Bitcoin is in chaos because of this prolonged blocksize debate.
People are looking for alternatives, but long-time holders of bitcoin don't believe in the traditional fiat model anymore.
However, there is a bit of a problem. Bitcoin has a much larger market cap than all of the other altcoins combined. The only crypto that even comes close is ETH, and ETH says on their own website that it's not a currency, but a smart contract token. Many holders of ETH deny this and are even offended by this. But it's not offensive, because it's the truth.
I'm not saying ETH is worthless, because it's a very valuable asset, but it's not a replacement for bitcoin.
But then where can you move your bitcoins to, if not for ETH and no other altcoin comes close in market cap?
Well, the best solution is to spread your wealth around in altcoins that look promising to you.
Personally I think Steem, Gamecredits and Dash all have very strong potential. Dash as an outright replacement for bitcoin, Steem for the social network value, and Gamecredits for the gaming culture.
ETH will be mostly useful for developers and corporations, not so much for home users. But I still hold some of them, just in case.
