Well this is a first. 

£17m is about 5,050 bitcoins - if you had mined these about 10 yrs ago, these would have cost you about £100 - ok slight exaggeration. 

Still, I'm keen to see how this pans out. How will you pay stamp duty?

If it goes through it certainly will not be the last. For one, overseas investors can avoid crippling bank fees. 

Interesting times, no doubt.
