one way is writing off your bitcoins as not yours. that money is not yours to spend. just forget about it. the more you look at it, the more you will just want to sell it especially when you see the value of bitcoin.
do you also do this and does it really work for you?
Regardless of how how knowledgeable you are about Bitcoin investment,, I dont think it will be so easy for you to just leave your Bitcoin in there and forget it it as if its not yours,, although I understand what you meant by to forget about it as if it it is not your own. But one thing is the most important thing for a Bitcoin holder, which is patience.
As an investor who wants to hold for a long period of time, even if you are looking at your wallet every day, you wont touch it because you already set a target for the market that if it reaches that, that is when you will sell your Bitcoin, so there is no need to say you should act as if you have forgotten about it.
Just make sure you are knowledgeable and invest the amount you wont need in a short period of time because that is the best thing.. Dont invest the money you will need in a year; make sure you invest the money you can leave in there for a long period of time.
