If I understand what you trying to say as in "Bitcoin fixed". I simply made the BTC the index(home page), since it's the mother of all crypto's lol. If you are referring to the image, I just ranked coins at the time of market price etc etc.
why not make a standards QR generator that QRs everything website adresses, wallets etc. and have window where a wallet adress comes out and then there will be a scanner showing a text saying number of digits and which wallet type it is/could be like ethereum bitcoin etc.
