Common sense goes a long way. It doesnt take genius to tell 5% per week "investment opportunities" are ponzi's, nor does it take a lot of faith to see BFL is actually producing state of the art products, making a shitload of money legitimately. There is also nothing unbelievable about them being able to produce asics, there are now 4 other companies claiming the same capability in roughly the same time frame and they all have far less resources and far less proven trackrecord.
Is it possible Sonny is running another con? Sure, but he would be an idiot to run off with your money with after already having spent 2 years in jail, a criminal record and with his name out in the open. Especially when he can make a crapload of money by just running his business as he has been doing.
TL'DR It makes absolutely no sense to assume this is a scam.
OMG!! A well thought out, reasonable post! Quoted for future proof.
