That's sad if you really have left nothing after all of those years but you still sold and got the cash.
That's true. I've cashed out on different rallys and always found a way to get back some coins – faucets, sig campaigns, before 2015 mining (started with GPU mining, later got some nice Block Erupter Cubes and Antminers). It was a wild ride and beside the coins and the money: 10 years in Bitcoin (and several altcoins) gives me a whole lot of memories and knowledge – good and bad ones.
BTW: it's always good to remember if you still you have some coins somewhere. I made some 0,00266
BTC in Dec-2016 per affiliate links to one service site – back in that days that was just 2$ or so. Yesterday, I've found that I still have these Satoshis in their wallet and transferred them to my Electrum … Well what was 2$ 4 years ago is now some 150$ today.
