In any technology, there will be a scam. As in blockchain technology especially in Cryptocurrency. Many people utilize this technology to commit fraud. Even after the heyday of Crypto in 2017, crypto experienced poor conditions. Many investors lose money when investing in ICOS. ICO seems to be a field to commit fraud.
So it impacted until now many ICOS and IEO difficult to attract investors. But if a lot of IEO and ICO projects are real and able to make money. I am convinced that slowly investors will re-invest.
