A lot of my friends bought bitcoins at the all time high, believing that the price would skyrocket to $20 000 or even $50 000 per coin. As you know this did not happen and the price dropped with more than 80%.
Oof.
I wouldn't have allowed that to happen.
I knew the bubble was done when someone who'd been aware of crypto for years called up and said he was going to buy $3 XRP. He got slapped upside the head.
Everyone I told about it got some from me for free. That helps.
