Same here. Got my first bitcoins to buy acid off the Silk Road. At that time they cost 12$ each. Found it interesting and decided to get a 1000$ worth beyond what I was going to spend. Been hodling them since - well most of them - sold a bit along the way when it looked like bitcoin might crash and burn. So I have cashed in over the years about 50k USD and still have enough BTC that I am just about a $ millionaire.
Of course it is a pity I did not buy more and panick sold some but still all in all I am not complaining. If the whole thing crashes to 0 tomorrow I still got my money back 50x and if not I am set for life.
