When you start to buy you will be led to believe that you are getting a fair-ish rate per bitcoin. Today for example about £8500.
Now the when you sign up and click to actually buy, they inform you that the rate has changed, increase it to £13,700 per coin, and tell you, you only get decent rates if you buy more than 0.07.
"Please note, the Bitcoin price has now changed. Please check and try again.
If you buy between 0.007 and 1.98 BTC, you get the best price."
However, they will not allow to buy more than 0.005 of a coin.
Be very aware, of these scam artists, use only after careful review and if you cannot get the service elsewhere."
