If my coin increases by 200% per night, then I will sell half. If the coin increases by less than 100%, I will look at the number of coins in my portfolio. Most likely a part of selling, but when there is a correction in the market, then again I will buy.
Investing in ICO is the one of the way to earn a lot but there's risky when you do that you can loss all your money or can be multiple of your investment. So im telling to everyone to be more careful and be wise choosing ICO because right now there's a lot of ICO show and came up and some of them are scam.
