Recalling my entry into the industry in 2017:
The first bull market - I knew nothing, just messed around, bought shitcoins, played with contracts, speculated on <on-chain meme>, in the end, all the messing around was not as good as just holding and winning passively.
The second bull market - DeFi, arbitrage, new project launches, primary market - made a few tens of millions. After the bull market passed, the big crash, couldn't do anything about it, a 40% drawdown.
The third round - finally realized that making money in the primary market, new project launches, research, and technology are key.
Buying <BTC>, no longer care about shitcoins, let them rise or fall, it's just a process.
