Saving is great, but there's probably gonna be a point where you want to cash out or spend your BTC on something physical. And at what point do you cash out and/or start buying tangible goods? Do you become greedy and hoard your BTC in the hope it'll be worth millions some day, or do you cash out when it's worth thousands and sit back on a tidy profit? Remember, it could all go tits up any day or even the day before you're about to cash out for your millions and you'll be left with nothing. Suddenly that few K you could've made seems a lot bigger when you're left with zero or only a few $.
