Hi, I've been mining mostly ETH for about 7 months and have always used Kraken to convert my ETH to GBP. I understand Kraken are going to stop the withdrawal of GBP this month. I have an account with CEX-IO, but the last time I tried to withdraw GBP I couldn't do it there either (don't know if it was a temporary glitch).
Just wondered how others convert crypto, especially ETH to GBP. I've found also that Kraken doesn't usually have a very good exchange rate due to lack of ETH/GBP trading, so could do with a more competetive exchange. There must be some Brits out there with similar issues?!!
I think you can consider opening an account in Euros, it should not cost you much and you can convert in almost any exchange out there. Kraken is a great exchange, it is a pity they don´t do pound now.
