Basically I say that Bitcoin is not the right place for you to treat the asset like other assets such as forex, you can indeed benefit from the up and down scenarios but it is very unlikely to get a big profit (unless your balance is equivalent to one Bitcoin), because we can see that in the short term the up and down of Bitcoin is only a few percent such as 5% - 15%, meaning this is an asset that is not right for scalping, and that is why many people say that if you want to get a big profit then you have to hold the amount you accumulate in the long term.
On the other hand, as a good investor, of course, you must have the right knowledge regarding how to execute the market at the right time and place, simply by knowing when is the right time to buy and when is the right time to sell, but if we talk about Bitcoin as the object, there will be a fairly long gap between the time to buy and the time to sell if you really want to get big profits, but on the other hand, of course, I will also advise anyone to always dedicate themselves to learning various correct market analysis strategies, but for Bitcoin, I think fundamental analysis is the most suitable.
That will not always right because if you use DCA method from a long time and you can collect many satoshis, you will see the profit will be bigger especially when Bitcoin price increase. You may remember when Bitcoin price is lower than $10k and then the price jump so high to more than $20k. That is a big profit, right?
The thing is you need to accumulate more and more for some specific time. But if you decide to trade Bitcoin, you may see a small profit but that will not be problem because you can make more profit and that means your profit will be bigger. This day, the price seems want to increase but the moves is slowly so it is not easy to analyze the market now.
