I'm curious, did you originally own more than 50? If not, do you have a plan for when you will sell? I know if I'd bought 50 bitcoins back in 2010 I would have sold them, or at least most of them, many times over by now.
There was a YouTube video explaining how to buy bitcoin and I got curious. I bought 50 because I originally wanted to but 5 and I accidentally added 0. I intended to spend 10 dollars but I accidentally spent 100 dollars. I tried everything to get my money back but it was too late. Fast forward to 2015 I remembered bought some bitcoin in highschool and I have my key stored in a flash drive. That flashdrive was like external hard drive for me at that time.
And you weren't tempted to take some money off the table when your $100 investment hit $100,000, $500,000, $1M, $2M? Or are you saying you've lost the key?
Well, congrats on your wealth! I occasionally kick myself for not buying a few when I got interested in it back around the same time, but I console myself with the certain knowledge there's no way I would have held on to nearly these prices. I would've felt the need to diversify away as soon as it became an appreciable fraction of my portfolio. A bitcoin millionaire, I was never destined to be.
