Cryptocurrency accounting

[Standby]

Hello,
I have case that client use Revolut as his bank account for limited company. From time to time he send some part of money to bitcoin account (as part as Revolut services).
How should be settled this kind of transaction? Ie. Client send £100, and within a few months he send it back £90 to main account, this remain £10 should be traited like capital gain loss?

Thank you in advance!

If your company sends £100 to Bitcoin and gets back £90, that’s a £10 capital loss so corporation tax applies.

It surely depends if there is anything left in the Bitcoin account.

If £100 is sent to a normal bank account, and later on £90 is sent back, then there is only a loss if the balance in the other account is zero (for example due to currency fluctuations) If there is still £10 in the second bank account, then there is no loss. If the £90 returned is the full value of the Bitcoin then there would be a capital loss.

I think about second case, when Bitcoin account is zero, so there is capital loss - which field in Ct600 should be used then?
