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.
Which I think these are the two coins that will eventually dominate the market forever, the reason why I said forever is that I have seen the best of most of these coins in form of altcoins and till now, none of them have been able to even meet up to one third standard of any of these two coins, so if no solid projects that I have seen other than these two coins have still not been able to dominate the market, then i don't see any other new coin coming up again being able to dominate these two coins or the market.
It is as if these two coins already have all the solutions to every problem that all these altcoins could think of and they fill in the space, so people will always go for these two coins rather than going for coins that they dont know. The devil that you know is better than the angel that you don't know.
