On the trading software, the floating profit numbers are still jumping, but Old Lin has already exited the interface. His screen has two windows side by side: one shows the exhilarating candlestick chart, and the other is the almost non-fluctuating Decentralized USD (USD) reserve audit page.
Old Lin has a nickname in the crypto circle, called "the dumbest trader." While others draw complex Fibonacci lines in front of candlestick charts and discuss obscure MACD divergences, his strategy is simple enough to make people laugh: always maintain a conservative position, only follow mainstream trends, and decisively separate funds.
It was this set of 'not looking at K-lines, not trading, not researching fundamentals' foolish methods that allowed him to turn 2100U into 75,000U in less than two months.
"In the crypto world, the real big money is made not by technology, but by execution power." This is a saying he often repeats. But only he knows that on countless nights of extreme market volatility, what allows him to sleep peacefully is not just discipline, but also that part of his asset portfolio that never fluctuates and is as solid as a rock—the portion that he quietly converted into decentralized stable assets.
01 Three iron rules of the 'Foolish Method'
Old Lin's 'success theory' has only three points, as simple as common sense:
First rule: Always use only 30% of your position
He does not chase highs or cut losses emotionally. When it rises, he locks in some profits; when it falls, he turns off the screen and plays dead. This allows him to always survive and capture the complete trend. 'Slow is fast,' he says.
Second rule: Only touch mainstream assets, only eat major trends
He does not touch altcoins or meme coins, focusing only on the major cycles of a few mainstream coins like Bitcoin and Ethereum. A confirmed trend is enough for him to last six months. He knows very well that frequent trading is equivalent to giving the market transaction fees.
Article 3: Fund splitting, never All-in
His principal was split into several small teams like an army. When the trend was unclear, only reconnaissance teams were sent; once the trend was confirmed, the main force would slowly follow. 'This is not cowardice; it's leaving space for uncertainty.'
Many people think he is too conservative, missing countless 'get-rich opportunities.' But Old Lin just smiles, pointing to his account curve—a line steadily rising at a 45-degree angle, with almost no major drawdowns in between.
02 When discipline meets systemic risk
However, that May in 2022 taught Old Lin the most important lesson. At that time, he was holding a position in a mainstream DeFi project according to his discipline, when the market suddenly crashed without warning. In just a few hours, the token price of that project plummeted by 70%.
His discipline and position management remained effective in the face of this shock—because he only used part of his position, he did not get liquidated. But the massive shrinkage of assets made him deeply realize for the first time how powerless personal discipline is in the face of fragile systemic risk.
The core reason for the collapse of that project was later confirmed to be the opacity of its stablecoin collateral mechanism, which triggered a death spiral during market panic. Old Lin suddenly realized that the 'mainstream assets' he carefully selected might also be built on quicksand.
03 Seeking certainty that does not rely on 'discipline'
This experience fundamentally changed Old Lin's investment philosophy. He began to ask himself: Is there an asset whose stability does not rely on his operational discipline, nor on the morality or ability of a project team, but rather on unalterable mathematical rules and completely transparent reserves?
His search ultimately pointed to the concept of Decentralized USD. Unlike algorithmic stablecoins or centralized stablecoins, true Decentralized USD seeks to construct a stable system that does not rely on any centralized credit through on-chain over-collateralization and complete transparency.
He chose to deeply research and allocate USDD. The reason is clear:
Over-collateralization, fully transparent on-chain: Every USDD generated corresponds to over-collateralized (usually >130%) BTC, TRX, and other assets, and the addresses and amounts of these collateral are 100% publicly available on the blockchain, allowing anyone to verify in real-time. This addressed his greatest fear of the 'underlying black box.'
Decentralized governance, rules locked: USDD is governed by the global community of the TRON DAO, with key parameters determined through public proposals and voting, and written into code. No centralized team can unilaterally change the rules, providing a rare predictability of policy in the traditional financial world.
Dual value of stability and practicality: USDD is not only a stablecoin pegged 1:1 to the US dollar, but it is also the 'fuel' of the vast DeFi ecosystem of TRON. Its demand comes from real on-chain trading, lending, and payment activities, forming solid intrinsic value.
04 New 'iron rule': Place part of the assets under transparent rules
Now, Old Lin's 'foolish method' has been upgraded to version 2.0. He still follows those three trading iron rules but has added a more fundamental asset allocation principle:
Allocate at least 20% of core assets to decentralized stable assets like USDD, which are secured by transparent and over-collateralized mechanisms.
This part of the asset, he refers to as the 'strategic safety zone' and 'ultimate reserve team.' Its role is multifaceted:
As a 'volatility stabilizer': When the market fluctuates sharply due to emotion or rumors, this part of the asset remains unchanged, allowing him to maintain extreme calm, unhindered by panic or greed.
As 'opportunity reserve capital': When the market experiences real panic selling and quality assets are discounted, USDD is his non-devaluing 'golden bullet' that he can use at any time to buy bottom.
As a 'profit retention pool': After he profits from trend trading, he exchanges a portion of his profits for USDD, which means turning 'floating and fleeting book profits' into 'stable and autonomous on-chain purchasing power.'
"In the past, my sense of security came from my discipline," Old Lin said. "Now, part of my sense of security comes from knowing that part of my assets exists in a system where the rules are completely transparent and cannot be privately changed by anyone."
From 2100U to 75,000U, Old Lin's story seems to be about the victory of patience and discipline. But the deeper revelation is that in this uncertain market, the highest level of risk management is not about optimizing one's operations, but about migrating assets to a more transparent and robust system.
While everyone is searching for smarter trading strategies, true wisdom may lie in recognizing that some risks cannot be avoided through personal skills, but can only be resolved by switching to a better system.
Your discipline can help you avoid most traps, but only a system built on transparent mathematics and decentralized consensus can protect you from systemic storms that even discipline cannot handle.
