That's right, at this time the percentage of successful projects is very small, so it's very difficult for investors and bounty hunters to find good projects. even scam projects are now made so good that they can fool investors.
You're right. Now is really a bad time for investment in ICO. Very few good projects worth investing in. And I advise you never to invest all the money in the ICO.
Your suggestion is correct. Many people invested all their money in ICO last year. After ICO went public this year, they fell a lot. They lost a lot of money, so you must seriously think about it before investing. Can you afford such a loss?
