Which altcoins from the last few years where there was a lot of positive talk about it has failed? And by failed, it means either it has went to 0 or it could be worth very little. Like it could been 50 dollars at one point and now 0.50.
I used to be very happy with Cappacity(CAPP) because it has a good AR/VR development,
and the price also explodes frequently in the hitbtc market. Actually their project is still progressing well,
but what I remember at that time was that the hitbtc market was hacked so that the market's reputation became bad and even the coins in it were affected.
Since then, I haven't followed the development of Cappacity anymore and they have completely disappeared for reasons I don't know.
I think it might be because of the market itself, because when I was still active in their community CAPP could only be traded on Hitbtc.
