I think investing with ICOs has a very high risk, among which we can lose all the money we invest, because there are lots of scam ICOs, even though there are also ICOs that can give you profit, but the percentage is 50: 50, of course this is very worrying, but if you invest with BTC the level of security is more guaranteed and there is a great chance to be able to get big profits from it,
Such an equal ratio is a golden ratio and worth accepting but ICOs no longer have such a golden ratio and nature, several ICO projects are still announced but for most investors, they are just thinking that someone is littering in public, there is not a gold field for them to dig like in the past, digging deeper is just dirt and sand and quite disappointed. Donations to existing projects are clearer in terms of rules and in the light of new names, all pretty much chosen, bitcoin is chosen less when the annual rate of return is quite reduced compared to the cost of investment
