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.
What you are saying is not true except that you have a trusted portfolio to give you the kind of profit you are saying on those rally, what they said about only getting profit in a long time is true, let me explain from the angle of those people who are using DCA on bitcoin, so actually there are people whom there monthly entry on bitcoin is not up to $30 so actually even a 12 months is still nothing to give the person the kind of profit that would make them see that they have benefited on Bitcoin so actually is only when the person continue to hold will you see them having some profits, so yes long term holding is the answer.
Both of you opinions are still directing to one perception in the area of Short term profitability.
My contribution is that the crypto market is volatile and since we don't know when that rally that is to bring profits will happen, engaging on long term goal is what would assure investors the certainty of making profits.
And while we may also consider short term possibilities regardless of the volatility, the value of our portfolios should also be considered because it determines the rate of your profit which I am sure 1% of profit will not be enough when the value of our invested capital is insufficient to give us appreciable incomes.
While our discretionary incomes may not be sufficient that we can acquire a large amount of Bitcoin on our first and only entry to purchase the Bitcoin, there would be no choice than to engage on long term investment which discretionary incomes nomatter how little it may be will give us the opportunity to be accumulating little amount of Bitcoins on the DCA while the volatility market is revolved in the uncertainty in maximizing your profits.
