Well i don't regret selling any of my Bitcoin because all that i sold was for a good course despite the fact that Bitcoin market value has increase significantly in recent time i have nothing to regret.
I have experienced earning bitcoin through investing and have already sold some of them. I don't regret selling them at that time since I have calculated and make sure that I will still have profit. Trying to earn cryptos is really challenging and I was hoping that by joining and reading on this forum I will be able to understand more things about earning. As of now, the price of bitcoin is slightly decreasing and though many people are waiting for the price to dump I just hope that it would not be now. Christmas is coming and many people seems like selling now for money.
