Try to take part in several ICOs spreading the budget. Some of them may be scam, some wont bring any profit,
others will show good results. Also try to take part in global projects, with experienced team and good reviews
"others will show good results"
Yes. But only a small percentage of it. ICOs aren't that much of a good investment now, compared to last year whereas you pretty much make profit with almost every ICO.
Why not just invest in the current reputable coins? It doesn't have to be bitcoin alone. There are lots of coins/tokens with decent use-case.
