I personally think that if you cannot hold your investment for a long time, then you should refrain from investing in Bitcoin. You have to remember that you cannot expect to make quick profits by investing in Bitcoin, if you think like that, then you are running on the wrong path. Bitcoin is an asset that will make you profitable in the long term, if you invest in the short term and cannot hold it for a long time, then you can sell it at a loss. So above all, before investing in Bitcoin, you must plan for the long term. And it is not the case that you have to invest a lot of money in Bitcoin, try to buy according to your means. Plan to hold it for at least one cycle or two or three cycles. But never think about making short-term investments.
It’s not entirely true. Bitcoin price is volatile so you can have profit as quickly as 1 day or shorter if you manage to purchase Bitcoin right before the price rally started.
It’s not necessarily true that you will only have profit on Bitcoin when holding long term while in fact Bitcoin price pump happened in spread time frame which means you can gain profit regardless how long or short you hold.
Holding it long will term can give a maximize benefits and it’s the best way on Bitcoin investing but not the only way to get profit.
Anyone that's after short profits like you said is a trader and not an investor because a long-term investor wouldn't be moved with little profits that he sees and sell because he is accumulating for his future and after reaching his bitcoin target. Profits shouldn't be what we should be looking at when investing if not it can make us deviate from becoming long-term investors which was our initial goal and turn into a trader.
Nobody says that bitcoin price cannot pump within a short time, but is that the right time for you to sell, and how many bitcoin is in your portfolio. When you sell too early, you have wasted all the time that you have used to accumulate bitcoin because you might not be able to buy them cheaper at that same price. This is the reason why long-term investment is the best so that you don't miss out from the compounding value of your bitcoin portfolio.
