ICOs might appear lucrative from a point of investor, but if you want to be a profitable trader, avoid the temptation of investing in every ICO you come across. An ICO succeeds if the project is solving a problem that has not yet been addressed by others. Banks have more money, so they can lend it to investors, which creates small businesses, which creates jobs. The team behind an ICO must also be technically sound and knowledgeable. Check the same on cryptocurrency forums where the ICO team is active. If the entire crypto community is enthusiastic about a particular ICO, consider investing prudently instead of investing a large sum.
