Dilema – possible scam?

Hi everyone,

My friend was researching crypto and he found this signal group or something that have constant wins on small gains and they trade with a bot.

If i caught everything up: you pump money into your account and your multiplier goes up sooo the more you have the faster you earn. Also it has this “invite per person bonus” that also adds to you multiplier.

I smell ponzi in this but this friend an his brothers assure me its legit coz thry talket with some 3 other guys(i only know 1) and they also are trading trough that group. This one guy got a company and a nice lloking courvette now and they believe him.

My father told me this guy scammed someone for 50k few years back and my fater is well known guy in my city and knows also most of the guys who earn a lot.

these 3 showed them balance and withdrawal logs as a proof it works, but once you withdraw you lose ypur multipliers and you must never fall on 0 or you will be out (if i recall corectly)

I meed advices from people who know this type of stuff better than i do.

I know this is ponzi 99% but cant prove it to him. I believe there is no bot or person who can have 99% of wins on the market.

Also winning in constant small amounts as i remember in crypto market you pay fee for every transaction IN THE MARKET not withdrawal from the wallet to bank to real cash
