However, I do believe that like 99% of them will fail in the next few years. The only question is will the new ones replace them? Will altcoins just keep popping up, pumping the number higher and higher, or if we can finally drop back to some normal number of good quality projects?
99% is little too over, there are still good altcoins to consider to invest especially ieo cuz u just need to do more research and not to greedy to blindly pick ieo and not doing research, altho most of them will reward u less reward than ieo phase.
if I look at ieo right now, the price is minus than the initial launch price. so ieo is not a guarantee. but it's true, ieo is good at the beginning of the phase, at least we can get ROI 2x. IMO, a good altcoins is top 10 marketcap, with a good project and have a big volume.
