Based on the level of sophistication of the question I'm concerned that it might not be the best investment for you. It's like when people ask me if they should invest in stocks, and the type of returns that they should expect. You should really have an advanced learning of the subject, and at a minimum know the difference between utility token, security tokens, advantages of using blockchains over databases, etc. For the the last example you would then be able to differentiate when a blockchain is truly needed for a project, versus when a database would do just as well or better, but the blockchain component is used exclusively for the purpose of raising money.
