I had invested one ICO previously, it failed although I didn't contribute a huge amount on it. A news yesterday made analysis on blockchain ICO projects, mentioning 92% of these ICO projects are failed.. Should I stop investing the others or any really potential ICO suggest?
Unfortunately a lot of ICOs CEO has its aim to get investors money so investing is dangerous. But you can earn crypto without investments with bounty or airdrop. Profit is not so big but it's not risky.
