I agree with you quite alright, but where I’m getting it confused is to the part you said long term investment is about portfolio growth because there’s a possibility that an investor can grow his portfolio within a period of one year or less, should that be the case then it still might be putting the person in the level of long term investor and this might go a long way to misleading newbies only to grow their portfolio within a short time and they might feel fulfilled that they’ve invested in long term and might want to sell off having noticed a little profit in their portfolio.
It shouldn't confuse anyone because everyone has his own goal on the quantity of bitcoin that they plan to accumulate. However, if a new investor is able to accumulate 1btc because that is his bitcoin target within one year or below, what prevents him from continuing to add more bitcoin to his portfolio in order for him to reach over accumulation status. If the person is aged or have health issues, that's not a problem but if you are still young and vibrant below 65 years of age, you should not start selling because you have reached your bitcoin target within one year. It's better to continue holdi and increase your bitcoin stash.
However, if you don't feel like increasing your bitcoin stash anymore, you don't need to sell your bitcoin but hodli for long term because that's when you will benefit more from your bitcoin portfolio due to the compounding profit overtime. Don't forget that the longer you hodli the better for you because history has proven that bitcoin price increases overtime and since bitcoin is in her early stage, you don't need to sell your hodlings. What will you use the fiat from your bitcoin sales to do.
Bitcoin is one of the best investments for the future so try and make holding bitcoin part of you because that's the key to success and financial upliftment in future. If you sell too many coins too soon for the reason of profit, you will regret it later when bitcoin price will be x3 or more of the price that you sold yours.
What if you were able to reach your bitcoin target within one year and bitcoin price at that moment is below your entry point, will you sell? This is the major reason why you should invest and hodli for long term to avoid losses. Profit shouldn't be your focus in the beginning, because your profit is not yet ripe for plucking.
