Hello,
Which coming ico are like ethereum and litecoin? I mean like their strong base, I'd like to participate in few ico and then earn some profit on their launch.
Litecoin was not an ICO, it was just a Bitcoin clone with regular PoW distribution of tokens.
What you are asking for is "what is the next ICO that will make me rich"? We all wish to know that, but guess what, nobody knows what the next x100%-x1000% is, and if someone knew I doubt they would tell you.
There's no easy way to get rich without a lot of research and a lot of luck, and im sure some ICOs will still make some people rich, but probably the days of huge returns are over with ICOs.
