Every day we see dozens of new ICOs enter the market
Do you think this is useful for the market and to what degree?

I agree that this time too much ico. But maybe this is a way to maintain crypto. Usually each ico has an airdrop and bounty program, which would be the most effective way to attract new investors in this field. It may be too much, but we need a new project to shape the market volatility.
If analyzed then an ICO has a negative impact and also a positive impact. When more and more ICOs can prove that many people are interested in the development of digital currencies. But on the one hand that sometimes when there are too many ICOs it can cause concern because at this time many ICOs are failing and it can automatically decrease people's confidence in digital currency.
An ICO should get a regulation because with this an ICO can be controlled. For me there should be government support for the development of ICO because it can convince many people of the interesting things that are owned by ICO. As reversed as the government remains silent, more ICOs may fail because of the lack of rules governing how an ICO develops.
We must start from now and try to convince the government, if this is allowed then it could be the development of digital currency will be hampered.
