I think ICO is a good way to invest for sure and opens lots of posibilities for both, investors and businesses. It can be considered a very good investment since there is a likelihood for the initial value to multiply within a short period of time. However, it is also quite a risky investment as there is a high chance of failure and you really need to be able to pinpoint the projects with the highest potential which have some practical application.
I also agree with you. ICO is a very good investment, it helps you increase your account many times. But consider investing in promising projects. Do not invest too much will be difficult to recover because not all ICO projects are successful.
