If a person thinks too much about profit and loss and other things before investing in Bitcoin, I don't think he will be able to invest in Bitcoin very easily.
Before investing in any sector one must think about profit or loss. No one invests where there is no profit. Investing in Bitcoin now can expect good returns in the future. Now no one can guarantee 100% profit by investing in Bitcoin. But if you can invest in Bitcoin and hold for a long time then you can profit. But if you plan short term then you will face loss instead of profit. So plan long term and try to implement it.
Many people say that if the price of Bitcoin is x, they will sell it, if the investment year is y, they will sell it.
My question to them is why should you sell one if you don't need the money at that time.
Can you find a better investment than Bitcoin?
Your goal is not the price, but your goal should be long-term. If the price of Bitcoin increases and if someone sells it, it is the mindset of the trader. If you think like that, you will not be a long-term holder. So no matter the price, you try to hold on long term. Yes, of course Bitcoin is the best to invest, I don't see a profitable sector like Bitcoin, if you can hold Bitcoin for a long time then you can definitely make good profit.
