ICO is long gone now, only very few projects use ICO to raise funds nowadays, we have IEO, DYCO and Polkastarter, these are the best crowdfunding strategy that are reigning right now, if you aren't going to take my advice and still want ICO projects I'd advice you do thoroughly research
Now Polkastarter is in the first place in terms of the number of IDOS held, which immediately after its completion give investors a profit of thousands of percent. I regularly fill out the Whitelist, but I have never been lucky enough to win this lottery to purchase new coins. There are too many people who want to participate in the IDO held by Polkastarter.
Polka starting is having too many requirements, only a few people that can also participate. It has very small spots for the users to participate in the token sales. It's not worth to try anymore. Im more interesting in coinlist.
FYI if my friend was making 2k USD to the 500k USDT just investing in pre-sale of flow project on coinlist.
