CGT with crypto loss + BTL gain all in same year

Lysimache

So I'm a bit confused about how BTL gains at 28% CGT tax rate vs CGT gains/losses at 18% for crypto or shares are handled. 

Cos you have different rates, only one allowance for both, and they both are one tax.  Brain can't cope.

Let's say I have: 

£50k of Crypto (yeah, I know, dumb)/shares losses this year. 

£150k of BTL gains this year. Higher band applies.

I haven't used my CGT allowance at all this year.
Am a higher rate taxpayer normally anyway.

How do I calculate my CGT? 

Is the tax calculation £150k gain less £50k loss = £100k total net gain multiply by 28% as the surplus is effectively on property? 

Is the tax calculation £150 x 28% less £50k x 20%? 

Or do I have to keep the two totally separate and just carry forward losses in crypto this year for future years, while I pay for all the gain in property in CGT at 28%? 

HMRC website says "If you have gains from both residential property and other assets You can use your tax-free allowance against the gains that would be charged at the highest rates (for example where you would pay 28% tax)." But I'm still confused. 

Handy to know as with the huge crypto losses this year I can always time my crystallisation of those to minimise my BTL CGT payment if that's allowed and maximise losses + CGT allowance? Cheers.

That appears correct to me (presuming you are already a higher rate taxpayer) from which you deduct your £12300 annual exemption.

The basic rule is that you set allowable capital losses against the capital gains that bear tax at the highest rate, so if the £50,000 losses on cryptocurrency was shorthand for £60,000 losses and £10,000 gains, you could set the £60,000 loss against the residential property gain, reducing it to £90,000 at 28%, with the £10,000 cryptocurrency gain being charged at 20%. The £12,300 annual exemption would further reduce the property gain.
