I am just recently getting into new crypto projects and dont know where to start from whatsoever, i do understand some projects are completely useless while some other projects can be promising, how to investigate on those ?
Based on my experience in investing, I would prefer investing into the trusted and top altcoins than investing into new projects.
Investing in new projects can give you more stress. Investing into new projects will not make you sleep because you will think "What if after I wake up in the morning, they already ran away along with the money that I invested?" Promising projects for you but not for others and even those "promising projects" still has a high chance to scam you. I always do invest into top coins because it's less stress for me and it has a lower chance to scam you so you will not worry of you having an anxiety.
