If you had the opportunity, would you do it?
For example, you buy 1 Bitcoin for 8000$ and sell it for 8800$ but the money goes to your Paypal account?
And you could do it over and over again?
Yes, I would do that if I get some good profits from doing it. It would be nice to have a consistent profit from time to time. And I will never exchange it for anything.
For me, it depends upon the situation, I can't say I would not sell it but if I would be able to get more profit on it then why not. But its a case to case basis, I would be able to observe it from time to time.
