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.
Just mentioning a few that I remember, because too many.
Usually these coins are often encountered as masternode coins such as agricoins.
but not all of them mean all masternode coins will just go bankrupt, there are some popular tokens that
once followed them also disappeared when they were famous, they are amepay, bonpay, canya and many more.
At least the tokens have been in the top 100 on coinmarketcap, but they had to disappear due to extreme market conditions.
