Yes, the wild swings in prices make for good potential trades but make no mistake about it: They are all schemes and scams. No exceptions. There's only ONE "reason" to pretend to "justify" inflation of more than 2-3%: Scam you out of your money. The bigger the inflation ("stake") offered, no matter the caveats, the bigger the scam. You have been warned. It's up to you to depart with your money as quick as possible or not, but don't claim ignorance: None will be around by the time the first years's stake can be quantified. Not a single one. Make a good note of it.
