I’m curious what Alt coins people are bullish on? The top 15 coins 5 years ago are very different that the top 15 now, so I’m curious what Alts will last and what new coins we will see in the top 15 in 5 years? I personally think that Etherum and Bitcoin will stay 1 and 2. As for the rest I don’t know but I think that NEAR is a wonderful project and will be top 15 in the next 5 years, I’m curious your guy’a thoughts?
Bitcoin and ethereum remains in its position but if we take a look at top 10 list in terms of marketcap value then you can see huge transitions actually so that it remains me that altcoins are never going to be the same forever. 
Maybe in the next 5 years I expect new coins to occupy the top 10 or 20 lists.
But i'm also open with new altcoins to replace the top 10 CMC in the near future. It will be inevitable especially if new projects will likely to get more interest from the developers because of its great utility case that will be mostly supported by the investors.
