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.
Also I am talking about coins that were at least in the top 50 or top 100 in coinmarketcap and then it just fell apart. I don't mean a coin that came out and everyone had praise of it and it didn't even break the top 100 on coinmarketcap.
Well now you can hardly get news of cryptocurrencies in the market that has failed because there are now ten thousand of cryptocurrencies in the market, and the ideas are not in a by way unique, just the same old ideas being reworked on in one way or the way and presented to the public.
Years back, there have been lots of cryptocurrencies that came out with unique ideas and a lot of people thought that these coins were going to be very successful in the market, but at the end they failed. One I can remember is the first space coin, known as SpaceBIT, which was an ambitious project, but ag the end it still failed.
