Well even I am seeing many new ICO's are a scam nowadays. Even the reputed ones who had a successful campaign running turned out to be a scam. But let's not ignore the fact that there are legit ICO's who actually are fair enough and can be trusted.
If you just open the altcoins Cryotocurrency section you will see alot of bounties , Ann threads and what not . But it's really hard to find legit ICO's from that hindered topics. That is why most of the ICO's start up signature Campaigns with the help of reputed managers to promote their ICO .
All as in venture investment - one of several hundred projects grows into something worthwhile. And this is with the constant monitoring and hard elimination of unsuccessful projects.
I think there is not too many scammers, but definitely opportunists, and people who want to take their mediocre idea and get yourself a free ride ...
... I have few hundreds usd and want to spend it wisely. I am thinking about buying ETH and leave it. ICOs are too scary for me now.
