I would save those 10 bitcoins for 7 more years and sell them then.
Might be worth a little fortune then!
Not bad. We never really know the value of bitcoins in the future so I guess it's kinda worth it to risk the wait of that long. As for me, I'd probably only hold half of them and cash the half just so I can enjoy some bitcoins. I never had that kind of free money opportunity in my life, if I get then definitely I will enjoy that.
If I got 10 BTC then I will invest it or save with me for a long time may be it will reach 10000$ after some time and then we will become rich on the other hand if the it will disappear from the market then it will be a bad luck.
