It is nearly impossible to find potential 50x coin. I would personally seek 2x 3x coins much better than seeking 50x. It is basically gambling buying those ultra cheap coins to wait a year.
I agree. You can't look for 50x coins, it's impossible to know. But 2x-5x coins are easy to spot out (Chainlink anyone?) during ICOs, and then you can hold it and potentially make more long-term.
You're both right. Unless you're psychic, there's just no way other than taking your best educated guess. Some have a gift for good guessing, others don't. Hehe
