A few days ago, I saw someone on Twitter saying that shorting 1x the coin standard will eat up the funding fee, so I tried it. Shorting 1x the coin standard will cost you about 30% annualized funding fee. However, this is not stable. Sometimes the funding fee goes to the short seller, and sometimes it goes to the long seller. If you short the coin standard, you will not get the bonus of the coin price rising, and of course you will not be affected by the coin price falling. This is probably how miners hedged back then.
