Don't invest on things you don't know. Plain and simple but will make more of your investment decisions easier. This isn't just for you but for those who may asked the same thing again. Trends are good especially if you're early but I'd tell you, don't be someone else's exit liquidity trends tend to fade fast these days as well.
That's right because most of them are just hyped in their early stages and they will just simply leave their investors once they get their money from them and stop promoting it further and make some useful updates that can keep up with their competitors. that's because they actually don't have any plan on how to further escalate their sales and connections, all they are working these days is just for hypes and once that is gone, they also leave and at the end of the day, all their investors get after that are false promises until they get bored.
