Don't ever forget the Volatility nature of these coins that can be very stiffened at times. And that is why one must be ever ready to avert the volatility risk as much as possible. In essence, I shall go along by few of my prior posters that Diversification is far more better for you in this regard , where you shall not be putting all your eggs in one basket. Apart from Bitcoin and Ether you rightly mentioned, you can as much as possible buy about other three potential coins with good features based on your research and invest upon. So that if any of their volatility falls on the negative side, you shall have few others that shall bears the risk.By then you are averagely okay, other than you loosing out on just BTC or ETH if the other way round submerged.
you got a point there my friend.
because you can choose both coin . they are both great coin . you really need sometimes to try your luck ,
they are both unpredictable . just like what happen last week . Eth crash and Btc .
you really need to take the risk . and Remove all your regrets
