The rest of my Bitcoin, will be sold when Bitcoin cross $100k.
If you don't mind, do you plan to sell all the BTC's you have? I would not do that and i don't think it is a good decision to take, especially if you are selling everything and keeping it in fiat. You can sell your BTC and enjoy some of it on things you want to spend money on, and you can sell some of your coins to reinvest it in other assets, but do not liquidate all your coins if you don't have a plan for it.
That's also what I have learn, it 2017 bull run, I sold all my Bitcoin, it was really huge in my local money and I'm happy for it. Nevertheless, I thought that I shouldn't, I mean just a small portion and then start the fun again by continuing to DCA.
So in 2020-2021, I still left some and again, continue what I do, or if I'm going to sell, it will be like in staggered sets or ladder principle, perhaps 25% and then see how it goes and then sell another 25% if you want to make another profit and then left some or like 10%-25% to HODL again and then continue with our journey.
