Even though the investor has time, if his goal is achieved, then he has more time left. He can use that time for work.
I don't understand what work has to do in Bitcoin investment and what time are you referring to that the investor will have? Bitcoin is not a job, it's an investment that you need to diversify your income into.
You have to wait for the long term. After buying Bitcoin, it is better not to sell it if the price increases a little. It is better not to sell Bitcoin thinking about your own profit. We should think about how to hold Bitcoin in the long term. How to invest and take Bitcoin forward. We should not sell it immediately, thinking that the price will fluctuate in the market.
I can relate with what you said that it's better not to sell when the price increases, so far you're on a long term investment plan. Selling prematurely will mean that you're derailing from your plan of long term hodl. To help you to stay focused you can adopt DCA method of accumulation, make provisions of buying from your discretionary funds.
