I owned 500 BTC and 11 of the most valuable collectable items that will ever exist, and I was left with just the one 25 coin. It is safe to say I will never own 500 BTC ever again in my life for as long as live.
Look on the bright side. You probably would have sold all your 500 BTC and 11 coins today.
The lesson need to be learn is to, only cash out a small bit of your bitcoin, if you absolutely need the money, and keep the rest in your wallet. The price will keep on going up in the the future. So use bitcoin as your pension, or long term investment. That is what I am doing right now.
