Using binance in the uk.

I cant deposit pounds anymore, so what can i do? I want to buy fantom, polkadot, cardano, and nano from binance, other coins i get from other exchanges (cheaper withdrawal fees or something like that).

I was thinking of buying bitcoin on gemini, and then transfering it to binance, as gemini have free withdrawals. Does convertinf bitcoin to other crypto currencies have any additional fees associated with it? Should i just buy from a different exchange? What ones would be best for the coins i listed?
