When you hear the word trading bot, arbitrage, academies, courses, investment platforms with abnormal returns (1% daily, 5% weekly or 10% monthly) you should always be wary. Why would someone good at trading seek further gain by selling you this "miraculous" system? They could use these services themselves, instead of paying someone to advertise/spam them around. It's the same story as "fixed" matches: why would someone sell it, if they are sure of that outcome? In fact, the odds would collapse and the match would be removed from the schedule due to volume anomalies (so many people betting on that outcome).

Why does this scam often work? Because 1% daily, 5% weekly or 10% monthly seems like little. Imagine buying an item for €20 with a 10% discount, the item would cost "only" €18 (10% is a small discount). In reality, 10% monthly is approximately 215% per year:

Annual rate = (1 + monthly rate) ** (12) −1
(where monthly rate, for example, is 10% = 0.10)

Do you know that by investing $1000 with a 10% monthly gain, thanks to autocompound, you would become richer than Elon Musk in about 17 years? Elon Musk's estimated net worth is about $230 billion. 

Where: Vf=objective, Vi=initial capital, r=growth rate (for example 10% monthly), t=number of periods

Yes, with a 10% monthly income and a starting capital of only $1000, in 17 years you would have the net worth of Elon Musk? Is it possible?

Remember that these scammers, even if they show you screenshots, could have a lot of burned accounts. They could also use delta neutral strategies (going long and short at the same time on the same asset and with multiple accounts) so 50% of the operations are correct.
What you should understand is that markets are unpredictable and no one can have a constant win rate over the months/years. Indeed, many authors have shown that there is always a part of randomness/luck even in successful investments. You definitely shouldn't buy random assets but set your goals (have a plan) and a risk threshold. If you study, you have the chance (albeit small) to beat the market. Remember that the win rate matters relatively and you should always consider the "expected value" of a trade.
The expected value is a fundamental concept in finance that represents the weighted average of the possible outcomes of an investment, considering both gains and losses.

Expected Value Formula:

Where P=Probability of a certain outcome, V=Value (gain or loss associated with that outcome)

The expected value of $40 means that, on average, every time you make this investment, you expect to earn $40. If the expected value is positive, the investment is considered favorable in the long run, while a negative expected value suggests that it might be better to avoid the investment.
For example, assuming you earn €20 in 80% of cases and lose €100 in 20% of cases:

-You earn €20 in 80% of cases (0.80 probability)
-You lose €100 in 20% of cases (0.20 probability)

The calculation of the expected value will be:

E=(0.80×20)+(0.20×−100)= 16-20=-€4.

That is, on average, every time you make this investment, you expect to lose €4 so it is not a good strategy (even if the win rate is very favorable: 80 times out of 100. When you win...you win little, when you lose...you lose a lot).
