Profit is going to come out when you sell bitcoin, you are losing opportunity because you can't hold on anymore. But if you sold bitcoin at good price there's nothing to lose, profit is there so don't regret if you sold some. The only regret and opportunity lose that is possible to happen if you never knew bitcoin and don't have an idea what it is.
Right, many people are still neglecting bitcoin because they can’t believe that there are online currencies. They are so close-minded and because of this, their loss opportunity here is to experience how saving bitcoin have been profitable for many users. If ever became so much popular in the future and its price somehow doubled again, I am sure that many people are going to regret how they ignored the chance of earning more than they could imagine in months, weeks, or a day.
Bitcoin’s use is still limited but who knows what will happen in the future, what will happen if it became legal, to be optimistic, what more can bitcoin do if it became legal?
Even with the aid of modern technology, bitcoin is still unknown by many people. I have been encouraging my friends to try what I am already doing, which is earning bitcoin, but they seems so doubtful of this digital currency and would ask questions like, "Is that for real?" and "How are you going to used or spend that?".
They would not believe that online currencies exist and that they could be earned through joining and signing up for signature campaigns and altcoins. If only they would try and would see that with the recent rise in bitcoin’s price, they have already loss the chance to have an income of their own.
