- If you can't implement what "Pursuer suggested", then I suggest to get rid of the "Search for Cryptocurrency... field" and instead, add those 29 supported cryptos to the top (heading - just use their logos) so users can easily click on them.
- At least try to offer it for the top 50 crypto-currencies.

I am only doing cryptos that are supported for cold storage devices( eg Ledger nano, trezor, etc etc.) If i do 50 I probably would have to do the whole 1600+ crypto's in the market (that takes time my friend). People have whined about not seeing their crypto. However, custom cryptos can be done at the users request, where a special link will be created within the site to create your crypto QR. I just like to keep things simple .
