just a feedback for you...
i was going to deposit but your BTC QR codes seem not to work
since my wallet is on my phone (electrum mobile) i only ever bother depositing with QR codes rather than manually typing addresses (and copy paste is not an option)

The QR codes generated on BetCoin work perfectly, and you say you use the same provider, so thats very strange.
i tried it many times, and generated new btc deposit addresses - each time, electrum says unable to decode qr data.

i believe this is a site error not user error, as ive never experienced problems with any other site's qr codes
