This is due the to number of coins entering the market everyday, the market is now saturated with scam coins and the worst part of it all is that they just make it harder for an investor to find good coins because it now takes more work and more research to sift through this new coins in a bid to figure out which one is a legit project and which one is just a scam. It's just sad
The only responsible person for this situation is only investor in my opinion. Just take a closer look - why so many scam ICOs entered market in 2017?
As for me - just because almost all people invested in project just reading the one pager or watching promo video on youtube, not so many people even open whitepaper, I don't say the read it and especially understand it.
So we are the part of the scam. No money to scammers - no scammers, it will become not profitable. So this kind of "fast" investors making troubles not for themselves by losing money, but for us too, for spending much more time to find something real
