When the bitcoin price is lower than the purchase price, we just have to wait for the next price increase.
This applies when you take Bitcoin as a short Investment plan and want to quit the market after making a profit. I am not saying that I don't consider it an investment. But, I'd instead consider it savings where I care less about the market price. Because I believe Bitcoin will gain massive ROI in the long run. If Bitcoin gives me a good return in the future, I will be happy to take it. But I won't be sad If Bitcoin doesn't give me a good profit Because, as I said before, I'd instead consider it a savings wallet.
There is no defeat in bitcoin investment, if they know the best way and know what to do when bitcoin experiences a severe correction.
This applies when you want to hold it for a long time. Bitcoin will continue to replace its ATH in the long run. No matter what your buying price is. You must be patient and hold tight until you see another ATH or a higher price than your buying price. I lost a lot in Bitcoin in the last couple of years, making mistakes that a newbie does. But I learned a lot since then.
