Hello @reeta0119
I see you invest wisely. Which is one way to back thinking ahead, congratulations on that.
There are probably those who.don't have ethereum or don't have BTC, and prefer to have other type of cryptocurrencies.. but, being these the main ones, the logical thing to do is to hold of both. Particularly I am also more with ethereum than with BTC. Hive some saved also, steem the same. Or a few others.
