I am still waiting for perfect altcoin, that
1) doesn't wait for to block to be mined in order to confirm tx, and therefore has truly instant transactions
2) has some sustainable retention policy, instead of keeping things in ever growing blockchain forever
3) with incentives to nodes, not just miners
4) with privacy similar to Monero
5) with functionality similar to ETH, but with ability to fix bugs in that functionality
Once it is out there, I will buy it.
Oh I think aside from bitcoin the main coin in the cryptocurrency.
Ethereum and Bitcoin Cash will also meet your standards in selecting coins to invest in.
Because ethereum already had a built trust and good reputation thats why there are a lot of ICO
Who uses ethereum as their token.
While in bitcoin cash it has a lot of supporters that help it to come out in the market.
