Anyone buying bitcoin now and expecting to get profits from holding will have at minimum to wait months or even years for that to happen, there is now way this can be classified as a form of trading as at most a trade could last a few weeks and at most a month, and even if a trader did something like that it means that during the time they made those moves they were not really thinking as a trader but as an investor.
There are differences between traders and investors. But, you could always have it together at the same time, how? Well, if you want to buy something and 15 minutes after you buy, that thing goes up in price then you could sell and make a profit.
But, if you are buying something and then it goes down, then you could hold it for a year and then sell it for a profit. You are the same person, and you bought the same thing, but depending on what the outcome is, you turn out to be a trader or an investor. This is why it is not really that much of a big difference between the two, the difference is what happens meanwhile. If you are willing to do it, then it's fine.
