<prompt> Human: My brother knows Im into being financially responsible. I save, I have an emergency fund, etcetera. A few weeks ago he tells me about this lecture or seminar that hes going to.Immediately the premise sounded too good to be true. So it probably was. I told him this and said I wouldnt attend. They, however, did.Today hes telling me about it pretty enthusiastically. Basically they require him to buy a piece of software for 500 euros and then hes in. This software is supposed to buy and trade currencies or something. It was rather vague. I tell him that it sounds like a bitcoin miner, and he admits that the lecturer even compared it to that. I tell him bitcoin miners dont turn a profit unless you steal electricity somehow, and even then its marginal.Anyway, his next point is that as soon as he convinces 5 other people to sign on, his 500 euros are reimbursed.This is where the red flags started popping. Am I being paranoid?  <response>: as soon as he convinces 5 other people to sign on, his 500 euros are reimbursedAnd they each do the same thing. Do you even need to ask? Classic pyramid. Run.
