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.
Wow that is really long term. What if
BTCBTCBTC suddenly had a major problem, then you'd be left with nothing.
As for me I'd rather spend all of that.

yes you are right, anything can happen in the future on bitcoin, therefore I prefer to make a profit every day, rather than just continue to hold for the long term. but some predictions about bitcoin very strongly that having a good future, so I hope it's true.
