Anything that is buying bitcoin and selling in 10 or more years is the best strategy, that is what big investors do, there are also those who want to invest and collect profits quickly, but since bitcoin is so volatile it is very difficult to determine when it will rise with great intensity to sell, those who are traders do it, but they have to do many operations, the investment is a matter of time, of having patience and of having a lot of mind in what you want no matter what happens along the way, they have to resist all the crises that arise and be faithful in the investment, in bitcoin it is safe.
I wouldn't call holding bitcoin for 10 years is 'buy and sell strategy' more like hodling stratgey, while I do agree that holding bitcoin is better because it has more potential profit, we can also take advantages from the swings in Bitcoin's price, short-term trading can also work. Though holding requires one to have patience and faith during the market crises, on the contrary, trading may be more risky but rewarding in the short run. All in all, it depends upon our financial goals and the risk we are willing to take, as both short term and long term approaches has it's own pros and cons
Agreed, in fact, in the case of Bitcoin investment, we must decide to invest for at least 10 years or more, because by researching the history of Bitcoin, we will know that Bitcoin fluctuates more in the short term, but in the long term, Bitcoin continues to increase over time.
That is, Bitcoin is a volatile asset in the short term, so short-term investment is definitely much more risky, which is why, a long-term holding perspective should be taken in volatile assets like Bitcoin, which should be at least 10 years and more.
In fact, when an investor holding his Bitcoin investment for 10 years or more, only then he can expect an positive effective result.
Because the history of Bitcoin proves that holding through long-term DCA is the most effective method of achieving success from Bitcoin investment.
