Well done! Sometimes its good to take some profits. Are you involved in any altcoin projects?
it is clear that OP does not mentioned about reason of profiting ,surely you did not read the OP instead just the title . because OP had sold Small fraction of His Bitcoin for a sole Purpose and that is to experience the feeling of having sold some BTC's .
In which brings us the Happy feeling from our own investment or even from our first Bitcoin payment as a Hunter.
Great for you OP in crypto or any other investment I think it is better to save our investment and don't be too greedy.
It is a good profit for you already for holding it and waiting for it to reach this high before cutting it off.
We shouldn't stress ourselves too much from it and learn to take a break or relax.
Yups Relaxation is what we have must because when the price of Market is completely falling that means we are in so much stress, but OP as a Long term Holder cares nothing about the present price.
