You don't sell bitcoins. You spend them.
The loan voice of reason. Bitcoin is suppose to be a currency, not a gambling instrument.
People gamble with currencies all of the time.
Not all like that Trading and invest is not a gambling, this need more trust and skill
Do not forget to luck, because no matter how great his skills without any luck, he will lose a lot of bitcoin in trading
Luck is basic of all your skill , but good luck can not be learned
yes of course, very difficult to get good luck, if you're really wanted, but sometimes it's luck that approached us, like when we bitcoin prices at a high level, and someone bought it. it was very fortunate friend
