Dont listen here but research!
Everybody here have own horse for best altcoin!
Listen to this suggestion and I would say the same thing too on make your own research because if you listen on people here they would just mention or advertise their own coin for which you might invest and put your money on the wrong coin.Better to research your own and see always which is always on the top on coin marketcap.
i right with u, but u can delimited here circle of research by give him some information about top coin, how to know is a coin is good or scam......., and it's not bad to give him some altcoins which u think is good
