There are too many altcoins are available in market,every day new ICO is generating and ICO's count will increase, some of altcoin and ICO's are scam project and be careful before you choose a good ICO project, in next couple of years there will be above double in current altcoin,some altcoin are very cheap and good project basis and if you buy some cheap altcoin this will be good profit in couple of years.Sometimes new projects with active team are those who disappear earlier compared to not so active new projects, yeah there are lots of new altcoins and we cannot really tell how legit they are.
