Moving to Denmark from UK. Taxes?

Moving to Denmark next year for work and would effectively be a resident.

Would anyone know if there are taxes to paid if I currently own a property in the UK but not having that rented out as my husband would still be living at our flat?

Would I have to pay tax on Crypto and Stocks gains (all in UK accounts)? I'm assuming I would have to pay taxes if I sell while I'm a Danish resident.

Any advice would be appreciated.
