There is a lot of hype towards ethereum, so in your opinion is that a good time for holding this alt?
Ethereum is one of Altcoin that has great potential for the future. So do not be surprised if many believe in Altcoin this one. And I think now is the right time to keep hold of Ethereum coins until the price is high again.
I would rather say: this is the best altcoin. Certainly, it has a great potential. As for about the price of Ethereum, I can guess that even in 2019 it will cost at least 3-4 times more than now. Hold ETH.
If the SEC approves the ETF (and this is probably already inevitable), then the money will go to the market. And in this case, the growth of only 3-4 times - too pessimistic forecast!
