Joanne from CoinCorner here. We're one of the UK's oldest and leading Bitcoin exchanges where people come to buy Bitcoin, as well as sell, send/receive and store it. Founded in 2014, CoinCorner supports 170,000+ people in the UK and Europe.
We also offer a Bitcoin payment gateway service called CoinCorner Checkout - essentially this service allows UK businesses to accept Bitcoin as a payment method.
I work in the marketing team and have signed up to My Local Services to network with other businesses in the UK!
If you have any questions about CoinCorner or Bitcoin, don't hesitate to ask me.
