Funny enough I don't believe that anyone who holds his investment for less than 4 yours is a long term holder except on cases where the person was able to accumulate so much bitcoin in such a short amount of time and maybe was lauck to invest in a time like this(for those that started invest maybe mid last year or from last year).
Holding an investment withing a duration of a year to four is no longer what we should be seen as short term investment, we
can even make the expected result within the first year of investing on bitcoin if we happen to fall under the right timing that after our investment, the market continues in bullrun on a sustained range, just as we have it from now, if someone is investing now and could be able to hold till this time next year, there is high probability of making more profits over his investments because of the post halving bullrun experience.
It all depends on the amount of bitcoin the person has accumulate over that interval of one year before you begin to talk about making of profit. If u do not have a sizeable amount of bitcoin in your portfolio you cannot be able to make this profit you are talking about ,especially if you are doing DCA it will take you time to accumulate a reasonable
amount of bitcoin.
