ico investment currently requires trust, don't invest if you are unsure and choose a trustworthy project developer. because many ico are scam and make investors lose money.
It is because of frauds that it is very difficult for many ICOs to collect even softcap. People no longer trust developers, because in 2018 only about 5 percent of ICOs were successful. The rest either did not collect the required amount, or turned out to be fraudsters.
