Many people buy SAT because SAT is cheap and the appreciation is easy. But now the SAT is expensive and the appreciation is difficult. So they sell the SAT，and naturally the price reduced a lot in just a few days. Is there the possibility that the sat can go back to its normal state？ 
Have you missed the past two months???
What SAT you are talking about?There has only been sat2 for some time.
If you believe in your coin then buy now the tons of it since you claim that it is inexpensive.
And when it goes up you can then sell it.
Every coin has two sides...
