You can follow the same technique that I follow before investing in any new crypto. From the top, every currency will look lucrative but you must pay attention to what services/product the company is commiting for. Secondly- check if the offered services or product sound conventional/practical/real . last but no the least, market for crypto is huge so only and only invest when you think that the services offered by the company can be benefical to you or to a partical group of people.
I wish you safe and happy trading.
