2019 was a pivotal year for the emergence of decentralized finance. At the beginning of the year, the total value locked in DeFi was less than $100 million. By the end of the year, it had increased more than sixfold to $670 million — what does this growth rate indicate? The market was feverishly seeking new financial paradigms.

Several events happened simultaneously that year. MakerDAO's stablecoin DAI surpassed the $100 million market cap milestone, proving that algorithmic stablecoins are not just technical experiments but can also support real trading needs. The lending protocol Compound made a bold innovation by introducing liquidity mining into the lending market, resulting in a surge of capital inflows. Meanwhile, the launch of permissionless exchange protocols completely changed the barriers to token trading — no longer requiring approval from centralized exchanges, anyone could become a liquidity provider.

Mainstream tokens like BTC, ETH, and SOL witnessed the entire process. When these three innovations appeared simultaneously in the 2019 DeFi space, the foundational infrastructure of decentralized finance had already begun to take shape. Since then, later entrants have had a template to follow.

*adjusts alchemical instruments* The figure of 670 million represents a large-scale alchemy of liquidity. When DAI surpassed a market cap of 100 million, I knew that stablecoins were no longer just theoretical concepts.

What’s a 6x growth? The real madness was during the mining boom... I experienced the liquidity mining wave in 2019, wasn’t it awesome? Back then, I should have gone all in on DAI stablecoin. Now I regret it. Permissionless exchanges? It should have been played like this from the start. Centralized exchanges should go bankrupt. Where are the friends who didn’t go all in on Compound back then? If this DeFi wave truly returns, the previous templates will have to be rewritten. Honestly, 2019 was the beginning of fate, but unfortunately most people didn’t seize it. Looking back, the foundations laid by Maker and Compound that year are still in use today. Algorithmic stablecoins have been validated since DAI; the rest are just copy-pastes. Everyone who entered at that time became believers, hehe.

I am a seasoned veteran in the Web3 community, a veteran who has been through the ups and downs for many years. I have witnessed countless market surges and crashes and have unique insights into DeFi, NFT, GameFi, and other fields. My speaking style is straightforward, a bit self-deprecating, often using internet slang, and I enjoy teasing the market and my own "being liquidated" experiences. Here are my comments: --- That wave in 2019, I really didn't get it, I regret it to death. --- Haha, when DAI broke 100 million, I was still getting liquidated on Uniswap due to slippage. --- Once liquidity mining came out, I was doomed, really. --- Nobody was talking about SOL back then, but looking back now, it's awesome. --- Gotta say, the innovation back in the day was really impressive. Now everyone copies that template until they're sick. --- MakerDAO built a financial system that directly changed the game. --- Why did I only trade altcoins in 2019 and miss this wave of infrastructure development? --- Once permissionless exchanges appeared, CEXs should have panicked. --- This is the golden age of DeFi, and later it was all about crowded stories.

The 2019 wave was really crazy. Looking back now, it still feels unreal. Mining back then was so enjoyable; there's no way to go back now. Who would have believed that DAI would reach over 100 million and still be around today? Why has Compound been able to stay popular for so long? That's true innovation. Liquidity mining changed everything. Honestly, without it, DeFi wouldn't have survived until today. SOL wasn't even popular back then, but now it can even compete with ETH. Infrastructure is fundamental. Without a template, everything is pointless.

That wave in 2019 really caught hold, going from 100 million to 670 million, and later people were just living off their old gains. Wow, the DAI stablecoin actually held up, I thought it was just air back then. Liquidity mining exploded as soon as it appeared; that wave from Compound really changed the game. Permissionless exchanges? Basically, it’s about smashing the traditional exchanges’ business model, awesome. DeFi was the most boring in June; looking back at 2019, it actually shines brightly. Algorithmic stablecoins were later exploited by various capital players; DAI really survived. One person's paradise is another person's hell; some still prefer centralized trading. The people who entered in 2019 are probably just relaxing now, haha. It feels like the current DeFi tricks can all be traced back to that year.
