I don't really know how they get to know, but from my own end I think it's very much easy mere reading through their white paper and road map, potential or fundamental projects are easily identified through their utility like what they got to offer, just like $near which is set to make crypto very seamless and easy to access by everyone in all aspects, normally a project which stands to solve a pressing issue in this space is sure to go parabolic.

$Near has solves tons of problems in crypto, just like how the BSC network which brought an alternative to ETH high gas fee, this is actually what contributed to the spike in price of BNB.
    I literally had gained a lot from fundamental coins than meme coins with just hype.

Am actually here for the long term.
