maybe it is already mentioned by other people here but i would like to say that bitcoin is more convenient to use as method of payment and bitcoin is reliable for long term investment or putting your money for savings and while you are keeping your money in bitcoin there's a possibility that you will make a profit from it .
nowadays most people are doing the same thing as well although it is not actually supposed to be an investment and it was created for transaction purposes but we found out that it was also the advantage of using bitcoin. we can treat it in different ways whether it is for currency, an investment or much better we will treat it in both ways because the good benefit of it is that we can just keep our money safe with bitcoin while its price is growing .
