WOOOSH The point is that it's terrible advice. My point is people who espouse how smart they are about something should put up or shut up.
1.) there are a multitude of ways to you can do this on a decentralized exchange DYDX as well. Or a Mercantile exchange like BITMEX.
2.) Funny you should bring up Bill Akman he publicized his short position, and another investor took a counter bet to him. That investor so happened to do it out of (speculated) spite. So not really a good example but since we're here Herbalife was investigated and not found to be an MLM, although I'll grant you that the SEC came RIGHT up to the line in calling them an MLM scheme.
3.) I'll move past the criminal enterprise portion as that's for courts to decide. With respect to binance specifically there are multiple ways to go short I'll post the straight forward versions. Cash settled perpetual swaps, Coin settled perpetual swaps, Put option contracts, Margin shorting. The way I would recommend people short bitcoin is cash settled perpetual swaps, you will be paid out as there are insurance funds that are VERY LARGE you can see what they are, that will pay out winners should losers positions can't be sold to the market.
4.) So does every exchange with respect to the market they serve, the smart exchanges actually want to be price neutral as they view as a business, both FTX and Binance CEO go on the record about this.
So you don't want to short BTC but you still think it's a ponzi scheme ... report it as such to the SEC. Accept that's a loss cause because bitcoin is deemed as property, furthermore a commodity and thus regulated by the CFTC.
I'll finish about the crooked casino portion... you can do this in a decentralized fashion with DYDX or another de centralized exchange. EVEN IF you didn't want to take the time to do that. RIGHT NOW you can go to IBKR and take a short position on the greyscale trust which is essence a short position on BTC. FURTHERMORE if you think these exchanges are crooked and are doomed to fail. Take a short position on the exchange it self. Binance and FTX have their own coins (which are probably securities) that you can take short positions out on.
Final words, how long must a market remain irrational before your prospectus is wrong about the market being irrational? The paradox is if you answer infinity, you may be "right" but you're still wrong.
