Yes, evil and wrong in so many ways.
I bought colocated miners for Bitcoin and it turned out to be a mess so I was offered repayment as an option. I said I wanted the Bitcoin I paid and they said they would return the Fiat value of the original purchase in Bitcoin so I ended up with Bitcoin but at a Fiat value 9 months later and ... I had to KYC myself in order to get it back when it wasn't required of them for the original purchase. I lost in so many ways and I would have been wiser never to have made the purchase in the first place.
Only spend your Bitcoin on small zaps! Or never spend your big bag for a bigger bag because you already have a big bag! Like buy a pizza with 2 Bitcoin if have 400 but don't buy a couple miners with 0.5 Bitcoin if you don't even have 1 Bitcoin.
