I appreciate your comment, and i agree with you for most parts.
I bought a couple of NFTs (about 3-4, iirc) upwards of 10 sol at SOL's ath ($250) all are less than 1 sol now
Paperhanding here, just as you mentioned involves DYOR. Not blindly holding on to projects... Sometimes know when to cut your loses and exit the market.
Nice post. Aptly written with no ambiguity. I don't totally agree with your diamond hand and paper hand view though. I've seen people dump good projects just to make a quick gain. It happens with NFTs too. A good example I'll give here is the Primates NFT on the Solana blockchain. I public minted at 4 sol and paperhands almost ruined it. That same day Primates dropped to 0.08sol (The work of paperhands) before it started picking up again. I sold at 7sol but now the Floor Price is over 20sol. So you see, paperhands are bad for projects and for you not to be used as exit liquidity for whales like you said, it's advisable to DYOR and know what you're buying into. I enjoyed going through your post. It's enlightening.
