2017 investing in ICOs is quite easy and the profits are also big, that's because there are not many ICOs like today and honest and responsible developers are included.
Now, I think you just stop investing in ICOs the greater risk and loss you accept.
Since 2017 most ICOs did not deliver what they promised and the unrest that this creates among investors forced them gradually shuru down the project. There is lack of regulation here in the altcoins sector and you will be wasting time searching because the number of legit projects are way less than the number of scam projects and failed projects combined.
The better and more logical process is to observe charts and buy Bitcoin. Because bitcoin will be big in future any day and you will never face such bankruptcy problems or so with bitcoin.
