Polo is irrelevant. Getting listed on Kraken is the win

Card payment is far into the future. Just look at Xapo. It took them $40mil in funding and a couple of years to get it running.

The devs should focus on improving the current software. Just use the Core BTC/LTC wallet and the Ark wallet and compare it side by side. Keep using until you really feel the difference. I'm talking about the user interface and function. The Core wallet is all function and zero bling, the Ark wallet is more bling and less function. Sending and voting is kind of erratic. When you send and click back on your address, the transaction you just made disappears. It reappears after it gets a confirmation. The local client should remember that it made a transaction and mark it as unconfirmed. The voting is also a bit confusing. I actually had to read the instructions for how i can change a vote.
