Bitcoin and Ethereum are two coins that have large volumes. Until now it seems to me that still dominates the Bitcoin market only. However, for a steady coin I guess there's nothing because all the coins, of course, the selling value is easily subjected to change.
The goal of the trade is to generate profit. And what I experienced to make a big profit for me is Bitcoin and Ethereum. So I believe that these two coins will bring thriving crypto and users and investors will continue to grow.
