Now I invest little in ICO, because the market is unstable and many projects do not raise capital. I prefer to invest in reliable coins that have long been traded on the stock exchange.
On what criteria you are finding the potential project because there are many people failed to find the potential project. Investing in ICO is always a good option but after listing in the stock exchanges the prices of the coin is not increasing and this makes people hesitate to join in ICO's.
