In order to be more profitable in Bitcoin investment, you must be experienced and the investment must be maintained for a long time. Those who benefited from investing have long prolonged their investment, even they still retain their investment. For example, MicroStrategy, El Salvador and BlackRock have been investing in Bitcoin for a long time even though they have already seen success from their investments.

Once you understand Bitcoin - you won't take it for any other thing on the market.
And you will definitely not trade/invest in it for a short-term gain.
Investing in bitcoin in long term is good but some people also trade it. Just that it is not good to use all your money to trade bitcoin bit you can use a very small amount of money like out of 100% of your money for it, you can use 5 to 10% for trading so that if you lose the money, you can easily forget about it. Investment is the best if you are patient but some traders can also make money l especially when the market is more bearish. Trading is riskier and can lead to loss of money for most people. It required patience and good money and risk management.
