Paper gains help no one. I spent a bit around the $1000 mark. I'd been sitting doing nothing with it and felt like it was time BTC financed some actual enjoyment. Am I desperately embittered? Nah. It was free profit that was spent and it provided a high quality time.
I wouldn't spend significant amounts on depreciating tat, but equally there's no point in leaving a vast fortune to a cat protection home after living your final years in one rented room wearing carrier bags on your feet.
If it fulfils its potential it'll continue to appreciate forever. None of us will be here forever.
I'd be surprised if quite a few people in here didn't believe exactly that. See:
