1. Investing in coins from ICO is a big risk, however I think that part of my money should be invested in such coins.
2. IEO is popular now, but it’s hard to say if these projects will be successful in the future. At least, after listing on the stock exchange, the price of coins is several times higher than they were at the IEO. The main problem is that not everyone manages to buy coins during initial exchange offering.
3. In my opinion most of the investment should be directed to cryptocurrency from the coinmarketcap top. Such investments are the safest, however, the possible profit may be less than from investing in coins from the first and second categories.
