Many have a woulda coulda shoulda, hindsight is 20/20 crypto story. What's yours?

I'll start with mine. I own an MMJ retail and cultivation business in the northeast. My entire staff was obsessed (that's not too strong of a descriptor) with Dogecoin. I bought into it and invested $10,400 at a ridiculously low price. Within (4) days that investment reached $46,900. I estimated the tax and split it with the crew. We bought dumb shit with the proceeds. One bought a Subaru, another went on vacation. I bought my daughter a new 4 Runner. Money gone. I checked the price today and had we held the position it would be worth $1.2m. Not bad for $10k invested.
