there are many reasons to learn new skills / sectors in crypto but none more than your edge potentially drying up in a certain area. I know many NFT traders who were forced to pivot or quit when that sector died. Same with gamers, or DeFi farmers; many lost their main sources of income. Cex trading is fairly invulnerable- while there are periods of euphoria and periods of death, this area is fairly robust (hyperliquid) and mastering this style of trading is somewhat durable. contrast that with venture or other areas (which have mostly dried up) and you are left with many full time crypto investors without any discernable edge / skillset. Onchain may eventually get to that point in the sense that there aren't nearly as many runners but we'll see; I still think it's fine for now.
