Buying Bitcoin within a Ltd company.

I’m about to buy £40k of Bitcoin which I plan to sell in approximately 18 months time.

Is there any advantage to doing this using the spare cash in my limited company and holding the Bitcoin as a company asset, rather than withdrawing the £40k as dividends and buying the Bitcoin personally?

Bear in mind that when I sell it, it will probably be worth at least £100k so there will be CGT to pay if I buy it personally.
