Kraken's a little ridiculous but I don't know of any other exchange that lets you short vs fiat AND has no deposit/withdrawal issues.

Just learned that Polo doesn't let you margin trade BTCUSD or BTCUSDt pairs using BTC as collateral, pretty fucking stupid. Had to liquidate BTC and convert it to tether. That carry cost also is absurd, thats like 20%+ a year right?Kraken's a little ridiculous but I don't know of any other exchange that lets you short vs fiat AND has no deposit/withdrawal issues.

A trade that I'm considering, short GBTC and long BTC at the right ratio. GBTC is at a large premium, that should decrease as the hype settles down. The borrow rate is 24% a year right now on GBTC (IB has shares), so its a little expensive to have it on but assuming this market cools down within 1 month, it shouldn't cost much
But I dunno, its such an obvious trade that there has to be a catch
Good points, perhaps the right ratio is to use the same $ amount in both positions. So if you are short $10,000 GBTC, get long $10,000 worth of BTC. If BTC becomes worthless overnight, you lose 100% in both. If it doubles, and the premium stays the same, you are protected. you would only lose more to the extent that GBTC 'outperforms' BTC in a % basis. And you would bank to the extend that it would underperform in a % basisThere are the "standard" two catches of:
* 24% borrow cost that you identified
* the risk of the short position being bought in
but in addition to this, GBTC has traded at a premium of 20% to 130% for most of its life. Until there is a specific catalyst for it to decline closer to NAV, it may be safer to only short it when the premium gets back above 100%.
Also there is the question of what ratio to use with this pair trade. You used the phrase "at the right ratio" in your post - but what is the right ratio?
Suppose you are long 9.3 Bitcoin for each 100 shares of GTBC to short.
Let's use today's prices of 2275 for Bitcoin and 370.00 for GBTC.
If Bitcoin doubles, your 9.3 Bitcoin are now worth 4550.
You gain 9.3 * 2275 = $21,157.50 on the Bitcoin long.
But even if GBTC rallies by "only" 60%, it rises to $592. (370 * 1.60 = $592)
You lose 100 * 222 = $22,200 on the GBTC short.
Net loss 22,200 - 21,157.50 = $1,042.50.
Even though GBTC went up by a much smaller % amount, you still lose on the trade, before considering the cost of the GBTC borrow.
