Become educated in this space, and just read everything. I would also think about short term and long term positioning for your purchases. For example, a long term position may be a token like Digipulse, a decentralized digital inheritance service built on the chain. Super undervalued and low price at the moment, and in my opinion a good buy now to HODL for the future. There service and value will surely rise in the future. They also just launched their main platform on July 1, and will allow you a 30 day free trial to test it out. Then you have short term buy and sells that you can leverage to build dollars for other financial moves/decisions.
