I am not an expert trader and do not have deep knowledge about the trades and how actions affect the market.
And to it, I think shorting also would generate more liquidity to the brokers or exchanges as the case may be since it involves not staying long in the market or waiting for lots of profit, and then, re-entrying again. In actual fact, it such practice should bring more gains to bitcoin
I agree that shorts might in fact be adding more liquidity to the market
Though I don't see how they could add more gains to Bitcoin over long term. When you open a short position, this creates some selling pressure. It doesn't necessarily drive prices down as it may be offset by a rising demand but it exists. When you close a short position, this creates buying pressure. Again it doesn't necessarily lead to higher prices as it may be compensated by a rising supply. There could of course be other effects as things are never that simple in real life, but all in all, shorts should be inconsequential long term
