Can't find ETF listed on Trading 212's website

this tracks bitcoin price right? should it be allowed in an ISA? (it currently is) if so then this is quite good as you can effectively buy bitcoin in your ISA using this ETF…doesn’t sound like it should be allowed.

edit: researched a bit and according to the website it says ‘ISA Eligible: Yes’ , so looks like it is allowed. seems interesting but 2% fee is quite steep.
