According to what you have explained, I understand the problem that you encountered in this process, there is no price set on bitcoin and tends to go down now, you are still not sure when it will rise again.
You already have good thoughts. If I am in your position I will divert funds from profit playing bitcoin 70% to real investment, so at least I still have some hard work to enjoy when I have to wait for bitcoin prices to rise again. But before that I will wait for the price to rise to sell 70% of the proceeds generated.
