It's impossible, a good market does have buyers and sellers. Imagine a market that majority of us only buy, of course it's already the peak and some of them will definitely cash out money because that's how trading works. The whole process of the market consists of this kind of cycle, those who're trying to accumulate BTC due to trend and will want to buy outside market price and that's the time they will sell it and the BTC will increase.

If there’s no sellers, then there’s no market movement because nobody can take the opposite side of the trade. The price will definitely gonna be stable and trading will become non-sense if that happens. Even in our normal lives, we have this kind of cycle in human nature, so it won't really happen.
