I believe in Crypto, I believe it has a future and its need in this world. If you don't that's ok, stay in the side lines getting grumpier and grumpier as time passes.
Cryptocurrencies are not mutually exclusive, this is not Highlander, there can be more than one. Look at Ethereum, already at half the market cap of Bitcoin and it hasn't affected Bitcoin's price in the least. What Bitcoin has over the others is wide adoption and mind-share. Smart money will diversify regardless.
