Personally, I believe that the Ethereum coin is the most promising coin to invest in. And it's never too late to invest in Ethereum, as the Ethereum coin is always in demand in the cryptocurrency market. And to get an excellent income, you need to make an investment decision now.
As volatile as the crypto market is, I still believe in ETH. It's the best best after BTC and I hope that it will rise soonest. Though BTC dominates the crypto environment and most coins including ETH rides on BTC going high, it's still promising. 2018 were the best days of Eth - generally cyrpto. Eth got to over $1200+ then.
I believe ETH needs a breakaway so it can soar on its own. It's currently at it's high point this year after being low in January. A big pump is what it needs and with a new security team coming up, let's hope for the best.
