Meanwhile only the second should is supposed to be the case of a real investor. You know I just want to advise on how your mindset should be when it comes to investing especially when it has to do with Bitcoin, I do tell my self in times like this that my profits are guaranteed (even if they are not guaranteed, it's just a way to lead your mind) and with that in mind I have no thoughts of selling , instead I buy more to get a better position.
Well, that might work on some, but I'm pretty sure that just by thinking or telling yourself that your profits are guaranteed, you are not going to become extremely confident to actually forget about selling, because those who panic when they see a decline, such self-said things don't matter to them because even a second person can't convince them about anything at that time.
You know investing in Bitcoin is not just only about investing, you also have to invest consistently (weekly) to get a solid position. To some people after even ten years of good buy their profits will not be too attractive, but if you work now on how to get a good position by simply investing consistently, and also hard work via job to get a bigger dictionary income for higher investment, your potential profits in future will be very significant.
So work now on getting a good position instead of thinking of selling.
That depends on your investment capabilities. If you are able to invest some money every week or every month because you can afford to do that, that is great, and you will surely have more coins and better profits that way, but even those who make one-time investments, they also can make good profits if they have bought their assets at the right time. The lower the price for your one-time purchase, the better your profits will be.
