Have you tried being older? Bitcoin would be a 21+ problem for me!

If your family had a PC at that time absolutely. Just wait for the first inklings and start mining. It was way easier at the start. You'd be able to get several thousands pretty easy. Maybe you get some visa gift cards as a kid for Christmas, dump em in there. Or even just go to any store and use your allowance to buy one. Then sell at the peak. EZPZ

Yeah, you can do that. Bitcoin is anonymous and you could earn it relatively easy when it first came out. If you want to get real fucked up with it you could make even more by appealing to those early black markets and use your age as a cover, but that's risk.

At ten you might have a computer that can mine a couple of hundred bit coin

At the start all you needed was access to any computer. Mine for an hour and come out with some bitcoin
