i will thank you and i will keep it in my wallet, because in history bitcoin has practically only increased its value, for me it's a very good investment

yes and that is what i am also thinking. to me in present time i even cannot think about to use bitcoin. i am only going to hold it for the price increase. because it is expected that in next few months the price of bitcoin will increase so high. i think that it will even cross the 1200 USD level.
Majority of users are hoping that price by the end of the year and that is the reason they are holding it and not spending it to earn higher profits.
You are right with and that is what I'm hoping for. Hoping that the price of bitcoin before the end of the year is going to be at $800-$1,000. And if that happens that 10 bitcoins for sure is going to be big bucks at all. And after holding it, I'm going to convert it to fiat very fast.
$1200/btc is impossible to reach this year i guess since bitcoins price is stable for now $680+ mark. Who knows it might increase its price drastically that would possibly reach that mark then many of us would be happy specially to those holder of such big amount of bitcoins in their wallet.
