I agree with most of the answers, which I would formulate as follows: for most people it is better to simply invest, do Buy and Hold or DCA. It's a simple way to make money with Bitcoin. For trading, it depends, the more short-term the trading is, the more knowledge and control of emotions you have to have to be among the small percentage that make it profitable in the long term, but there is also an interesting point:
Yes. They are not mutually exclusive.
In my opinion they can be combined but trading in the medium term as a minimum, which would be to take advantage to buy more in bear markets and sell at specific times in bull markets, not to be buying and selling all day long.
