“Family, hurry up and buy XX coin, I have already invested heavily, this time the goal is to multiply by 5!” “Trust me, follow my operations, I guarantee you will make money, if you earn, we share the profit, if you lose, it’s on me!” Do you often hear these kinds of words in live broadcasts and communities? These people who call themselves “signal teachers” or “professional mentors” package themselves as “crypto experts,” but in reality, they are just a group of butchers who cut韭菜. Last week, a sister in my community followed the so-called “signal teacher,” and lost 180,000 in a month, only to find out that the teacher had already blocked her.
I will directly expose this scam: all the active signal callers and 'teachers' who ask you to follow their trades are just here to take your money. Their tricks are actually very simple: Step one, they package themselves, flaunting fake profit screenshots to create a 'master' persona; step two, they incite emotions in groups and live broadcasts, using phrases like 'high returns' and 'guaranteed profits' to attract retail investors; step three, they recommend cryptocurrencies they have already invested in, encouraging retail investors to buy in and inflate the price; step four, once the price rises to a certain level, they secretly sell off their holdings, leaving retail investors stuck at the peak.
Many beginners believe signal teachers because they don’t understand the market and want to take shortcuts. But remember, there are no shortcuts in the crypto market; those who can really make money never actively call signals. Those signal teachers are either trying to earn a 'cut' from you, collaborating with project parties to get commissions, or directly taking advantage of you. In the first half of 2025, over 100,000 users in the industry lost money by following signals, with an average loss amount reaching 80,000.
It's time for practical knowledge. Let me teach you 3 tricks to identify signal scams and avoid this big pitfall:
First, anyone who tells you 'you earn a cut, and you bear the losses' should be blacklisted. True professional investors would never collaborate in such a way. If they really had the ability to earn consistently, they would have quietly made a fortune themselves without needing to rely on your small cut. Moreover, this 'cut model' is inherently unfair; you share half the profits but bear all the losses. Do you think that’s reasonable?
Second, look at the cryptocurrencies they recommend. If they are only recommending some unknown small coins that have already multiplied in price in a short period, it’s definitely a scam. Most of these small coins are worthless, and the teachers recommending them are just trying to offload their positions. Truly valuable mainstream coins don’t need teachers to signal trades; everyone knows their worth.
Third, do not entrust your funds to anyone for management, and do not let anyone know your trading password. Some signal teachers may ask you to hand over your funds under the pretext of 'helping you trade' or 'managing your trades' or ask for your trading password. Once you give them your funds and password, your money is essentially gone; they will directly transfer your funds away or use your account for high-frequency trading to earn fees.
Let me share a real case: there was a so-called 'master' in the crypto circle who recommended a small coin in a live broadcast, claiming he invested 10 million, aiming for a 10x return. Many retail investors believed him and rushed to buy, causing the coin price to rise from $0.01 to $0.05. Just when retail investors thought they were going to make money, the price suddenly plummeted, dropping 90% in one day. Later, some retail investors checked the on-chain data and found that this 'master' had bought large amounts of tokens before making the call, and had sold everything after the price increase, making over 2 million, while the retail investors lost everything.
Lastly, let me remind you: investing is your own business, and no one can help you make money. If you don’t understand the market, start by learning, don’t rush to trade. Instead of trusting signal teachers, trust your own judgment.
