I have some bitcoins and found a secure way to keep them. What do I do with them now?
I'd recommend to keep them, the price will go higher in 2-3 years.
Captain Obvious:
If you really want to buy something, then decide first, what you need or want, and then find a way to buy it. BTC is somehow convertible and legitimate way to pay for goods and services, so it's not that hard to get what you wan, if the price is right for you.
