Almost you need about 10,000 SATs to get one dollar, and for that SATs to have a value, bitcoin should go up to a very high price, perhaps 100,000 or more, which means that you have to wait a long time before it has value.
we can say stacking mBTC or it will have some value in the future but you cant say SATs, its too early to say about it.
Bitcoin is good and you can work hard to get mBTC.
