It comes back to you, I sell not to avoid losses, so experience regret if the price continues to rise like what you do, it has become a target and I have arranged it in my investment plan, because what is the key to an investment is to save to get more, and we must have enough in life so as not to be greedy.
The most important thing in investment is to stay on track with your own goals in the financial world, as I mentioned you can talk price or time to sell your holdings, and you must realize what you have to achieve.
Well, it's quite sensible to be tempted to sell no matter what kind of investment plan you have, seeing your money grow like that is one of a kind achievement that not many people experience. I personally wouldn't call it greediness if we're willing to wait more, but patience on a proven investment that will definitely pay off in the upcoming years. The temptation will always be there, but I highly doubt I'll give in anytime soon. The key in holding bitcoin is to not be in immediate need of money, so you're not "forced" into selling earlier than planned.
