I think better strategy would be Buy the DIP, sell at local high, open short, HODL and sell at local low. Rinse and repeat. Indefinitely. Yes, it is easier said than done. But for me, it is easier after around 6 months of watch, learn, and execute.
We are not discussing how to buy bitcoin as a day trader, what we are discussing here is how to accumulate bitcoin and hold it for the long term with the different strategies used in accumulating bitcoin depending on your income source. If you open a thread next time, learn to know the topic of the thread you opened so that you will not spam the thread with your post. Since you are a newbie and you're in this thread, you should accumulate bitcoin with the DCA strategy so that you won't want to put all your money in bitcoin at a time. With the DCA strategy, you can use 10% of your salary to accumulate bitcoin when you are paid a salary. The DCA strategy will allow you to accumulate bitcoin without deciding if it is the right time or not to buy bitcoin. You should also keep an emergency fund that will help you solve your unforeseen problems so that you will not depend on your bitcoin to solve them.
