I just remembered a topic that many people might still be afraid to mention – what is losing the peg and why is it so terrifying.

Maybe you still don’t understand, stablecoins exist with a single purpose: to keep the price stable. For example, USDT, USDC, or DAI – they are designed to always be worth 1 USD, regardless of whether the market is crazy or not. This "peg" is the price anchor, keeping stablecoins closely aligned with the real value of the US dollar.

But what happens if one day, that stablecoin suddenly can no longer maintain the 1 USD value? If 1 USDT drops to only 0.95 USD, or worse, if 1 UST falls to 0.10 USD? That’s when the loss of peg occurs, and that’s when everything begins to collapse.

I must say, the LUNA – UST incident in 2022 was the worst disaster in crypto history. UST was a stablecoin of the Terra ecosystem, and it used to be a giant, ranking among the top stablecoins in the world with billions of USD. People trusted it, invested heavily. But then one day, what is losing the peg if not the start of a massacre? Its price dropped from 1 USD to 0.9, then 0.8, then 0.3, and finally just a few cents. No one could believe how fast it happened.

When UST collapsed, LUNA – Terra’s native token – was also dragged down. Its price plummeted from over 100 USD to below 0.0001 USD. Do you understand? Do you understand? People lost hundreds of millions, some lost tens of thousands, and some completely wiped out their assets. Depression, loss of direction, and there were even sadder rumors after that crash.

So why does losing the peg happen? There are a few main reasons I see clearly. First is the lack of collateral assets. Imagine an exchange issuing 1 billion USDT but only holding 100 million USD in reserve – that’s when trust collapses. Second, stablecoins can be attacked or deliberately manipulated to devalue, causing panic selling among users. Third, and this is the case with UST, is the weak algorithmic mechanism. UST had no real USD backing, only used LUNA to "balance" – and when the price fell, everything collapsed like dominoes.

As someone who witnessed that event, I want to remind you of a few important things. Not all stablecoins are "safe." If you ask what losing the peg is, you need to understand: it’s a red warning signal. When you see that happening, withdraw immediately before it’s too late. Always choose stablecoins with clear collateral assets, like USDT from Tether, USDC from Circle, or FDUSD, TUSD, DAI – those with more transparency than UST in the past.

Finally, I want to say that the "peg" is the string that holds trust. When that string breaks, it’s not just about losing money – it’s about losing faith in the entire system. LUNA and UST are blood lessons for the whole market. Read, remember, and stay alert, so no one has to write a sad status: "I quit crypto, I wish I never knew about it…"
