If actually Bitcoin is the subject matter then buying and selling within the period of one year apparently has nothing to be called anything related to investment but trading because one year is too short for your investment to experience the power of compounded value of your investment, a cycle which is four years would have been better to be described as a short term investment in my perception while four to 10 years or more can be called a long term investment.
Okay I have learned something today, atleast you have given a timeline for short and long term Bitcoin investment. Most people who target to buy during the Bitcoin halving are short-term traders, and that's a very wrong investment approach. I know people who are currently disappointed with the price of Bitcoin because they thought it would have reached $150k. But long term investors are not perturbed because they are still on profit or are not selling.
I so much believe that learning always took place in everyday of our life, because knowledge is really power indeed, so talking about short-term investment, those investors that always make use of short term investment i see those investors as a gambling, because they are betting not investing, they are just for quick money making not to wait till dip finally happen, so buying in the dip and hold in a long term investment is the best.
As a no coiner, depending only on buying the dip to accumulate bitcoin will also put you in the position of gambling with your bitcoin investment as well because you won't accumulate a good amount of bitcoin waiting for a dip that may not even happen today or tomorrow. Buying the dip is actually good if you have enough liquidity to buy the dip; it easily gives profit and allows you to increase the size of your bitcoin very fast, but before you use the buying the dip strategy to accumulate bitcoin, you need to be accumulating bitcoin with the DCA strategy so that you will be consistent in accumulating bitcoin in the market and be building up your bitcoin portfolio gradually while you patiently wait for a dip to occur, and if a dip doesn't occur, you already have an ongoing DCA strategy that you are using to accumulate bitcoin consistently, and you have nothing to lose.
