I sell my coins earned in bounty companies and bought for sale. I sell coins when profit became profitable. We are all engaged in business, all in different ways. But for all who work, the business should bring income.
I also sell my coins for good purpose, and most of those were used to gas up my transactions. The cycle was just a recurring activities in trading, and if in need of money I will certainly dump it in the same manner that selling while at higher value definitely provide me sustainable profits.
