Most ieo's were profitable as well as this one if you bought at the right price.
MLM pyramid schemes are also profitable in some cases. Would you invest on such schemes? Yobit is creating a lot of coins out of thin air and most of these are created where there is no blockchain existence. Do these projects deserve to be existed?
This isnt a pyramid scheme but for sure you can apply many rules of a pyramid to it, just that yobit only takes fees. Coins are sold and a 100% buywall is in place. It is more like a lottery ticket for the ones buying at ieo price and a high (sometimes) low volatile trading game. Many people love it and join yobit because of it. There are zero risk spots as well as extreme risky spots. The trader decides what risk he takes. Is it kind of useless and not contributing to crypto? Yes it is absolutley pointless other than it gives smaller traders a chance to win big and attract some gamblers to the crypto space. Many traders prefer this after losing to scams or pyramid schemes without knowing it was one. It is only a tiny part in the whole crypto universe so to be very ethical about it is a bit strong.
Yobit created so many investbox coins it looks like because devs were taking advantage of it to run their schemes. They also do investboxes for btc/eth/doge/waves and give free forks and airdrops like liza/yo/sex/yoda/air that you can put in the investbox. People complaining about this are also the ones buying scam coins with no research enabling people that harm the community. If i like to play around with a yobit coin what is wrong with it? I am not an idiot risking too much.
