I am surprised that they don't go beyond the top 10 coins in market cap to find hidden gems.
They haven't proven anything yet. In this space hidden gems can just as easily become hidden dump holes since utility doesn't matter. I know enough coins with pretty decent utility that actually deserve to be up higher in the overall list, but they don't get any serious exposure because the hype only concerns a few top coins. What other than the listed coins have proven to be worthwhile according to you? In my opinion Monero has been decent, Byteball and Digibyte. These coins however won't ever be able to climb up the crypto ladder due to how this space works. Bitcoin and Ethereum will probably be the only main coins....
Agree, even on those coins you had been mentioned do really have that feature which is really more better with bitcoin and Eth itself but still they cant really able to manage to go into the top. I do somehow believe too that hype is really adding or one of the factors why such thing do happen. Basing on the rankings specially on top 1-10 they would stay up for a while there might be changes but it would takes time if a certain coin would gain another buzz. This is somehow basing on popularity.
