Hi,
Thanks for your response. It was not bitmixer.io as I could see their service is stopped. It was
https://bitcoin-mix.com/. It only says dissolved when you click on their trading name at the bottom which directs to companies house. There is a link to this dissolved company and this website
https://cryptoforexltd.biz/?a=home as they share the same director and the same address in the UK. I am in touch with them now.
I appreciate what you are saying but it is difficult to know which ones are solid and reputable, especially when you are new and the site gives the appearance of being legitimate.
If it is gone then it is a hard lesson learned.
