You invest BTC (or ETH or fiat or any altcoin) to buy some new tokens and they will get you 10% of your holding everyday but value of the token will decrease consistently and at some point it will value less than 1 satoshi and then no one will be ready to buy those tokens.
AKA a Ponzi scheme.
People are saying it's a HYIP/Ponzi scheme so is it okay to only post in Gambling sections and garbage sections since Gambling section is officially for "Gambling and all "investments" that are so risky they might as well be gambling (HYIPs, pyramid schemes, etc.)"?
Again, if Yobit rebranded their InvestBox into GamblingBox there would be less concern about it. They they didn't promise 10% daily there would be less concern about it. It would still be utter shit but it would slightly less of a fraud, perhaps enough for it to be called a shitty gambling scheme instead of a scam.
The amount of mental gymnastics employed here to justify involvement in a scam promotion is thoroughly disgusting. I will start adding neutral ratings for anyone carrying this "10% daily" shit in their signature. Luckily for you yobiters you're sufficiently dumb to be considered injudicious rather than malicious so no red tags, for now.
