You have said it all, the simple strategy is buy at low and sell when the price reach higher. Determine the appropriate time of this circle, which is the hardest part to do. You need to stay active always for observing the market and price movement. Stable coin price don't change much, though all together it may cost a bit. Personally I like to hold for long time.
That is the simply strategy and yet very effective method. So can simply buy at low price or stack sats as many as you can and sell on the top before it blows off. It's just the matter of timing on where you are going to sell, so this is also very important.
And then we have the short term trading, just trying to squeeze profits as they can, probably 10%-20% profit in a month or two is not that bad.
So there is no secret formula here, it really depends on how you want to take profit here, you wanna be a a long term holder, or short term trading, its up to you on how you are going to use this kind of strategy and see how it will fit your goals here.
