I think so far Eth,Waves really deserve to be considered as altcoin which has good chance for future investment.
Because currently there are several ICOs that use flatfrom from both these coins so that it can add popularity and population of its users.
Yes, the price of ETH is now increasing, but we do not know what the future will be like, but it's a coin that is superior to other coins.
Ethereum was the next coin i want to hold by bitcoin, they are different coin but i know eth has also potential, the price now was increase and i think its a good thing to hold.
