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.buying the dip is just one of the strategy of buying or accumulating bitcoin, but not the best. one of the best strategy of buying bitcoin is the DCA strategy because you buy without considering the market condition, because buying only the dip makes it looks like a trader or a person who is in for short time profit or taken advantage of the dip in the market. it is best you combine the 3 strategy to make a good accumulation process .
