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.
There are many but Im not sure whether they are still on the list. Example ptojects like ncash and some of those listed on binance especially the fantoken. Youll noticed that their price has gone down. But of course there are much more on ido projects that have been went from high price to nearly zero after few months. People should be careful on choosing some project to buy for long term.
