Most of the crypto investors that have lost their capital didn’t lose it to the market conditions. There are always the things that are overlooked and go with the denial. The listed below are five of the most common mistakes that are repeated every cycle by participants of all experience levels.
1. The non-reversible mistake: Private key compromise
Wallet hacking was the most expensive attack that happened in the first half of 2025 and the value was a shocking $1.7 billion derived from 34 different exploits. The total amount stolen reached over $2.17 billion by mid-2025, according to sources like Chainalysis, which in fact already matches the entirety of 2024. A real-world example of this attack took place back in the August 2025 incident where a single user lost nearly 783 BTC as soon as scammers impersonated hardware wallet support staff. They gained control over the recovery phrases through an encrypted chat.
The only item on this list in which failure is unavoidable is considered to be key management. The Blockchain has no “undo” button, which makes it different from the traditional methods. There is no exchange, no protocol, and no judge’s order that, on any sort of mass scale, is able to recover an already transferred on-chain asset. In the case that your keys are compromised, the assets are also at risk and you must shift your assets to another wallet.
2. Relying solely on the exchanges
Exchanges are easy to use and are convenient but they are not secure. Not safe in the way that a hardware wallet is safe.
Bybit maintained custody of customer assets. The exchange was hacked for $1.5 billion in Feb 2025, which in turn became the largest individual theft in crypto history. FTX kept custody of customer assets and later FTX became insolvent. Billions are stuck in bankruptcy for years. Such a pattern keeps happening every cycle due to the fact no one seems to actually learn the lesson.
3. Using leverage in the wrong way
10x leverage on a position means that after the 10 percent move on the wrong side, your position will be wiped out completely if running in an isolated mode. The crypto can give such a type of move in just a time period of 1 hour. Funding rates also have a significant impact on the running positions and can drain you daily on the help positions. The liquidation engines primarily exist to close your position out and have nothing to protect you. The new traders become eager to earn more profit as soon as they stack wins promptly on leverage, followed by beginner’s luck. This is the real danger. It is so because those wins will feel like a skill and will boost confidence. One wrong move and all of that will be erased entirely.
4. Following the crowd and avoiding the concept of DYOR
More than 84 percent of the people buy on FOMO and not based on research. The influencer’s followers lose around 7.9 percent on a monthly basis and it becomes 62.8 percent yearly. The market’s social volume gives an idea about what the people are going through at the moment but the truth stays hidden. The crowd is wrong most of the time and you can’t rely on the noise to point out the exact tops and bottoms. Before making the decision to buy, there are a few things to be considered, like going through the whitepaper, verifying the team’s background, and checking the vesting schedule. For example, if 60 percent of the supply is to unlock in 6 months, this factor is going to likely result in a negative effect over the price action of that respective asset.
5. The buying made during euphoria and panic selling
It feels smart when it comes to selling dips and stacking up during the buying pumps. Both look logical but destroy portfolios to a great extent. The human brain treats the recent price as the permanent thing. For example, a drop of 40 percent will feel like 90 percent is the next possibility and the pump of 200 percent will feel like there is still more room for the price surge. The harsh truth is that neither of this is true. The market participants who survive the crypto market cycles make the plan before making a move and stick to that. The price going against you will not prove you wrong; the invalidation must be mentioned in the plan.
