I just wanted to add a few ideas that I came up with..
Set up a crypto futures account (Binance, Bitmex etc) - I think any profits would be liable to CGT though?
Find an overseas/non-FCA regulated spread betting platform that offers crypto - this would work I just haven't been able to find one - does anyone know of one?
Open a short position on a bitcoin proxy (Microstrategy, Argo Blockchain) - I think this is my prefered option at the moment.. not ideal though.
Adding a some tags - Bitcoin, Crypto, Short, Hedge, Futures, Spreadbet
