How cool would it be to have a Xapo like debit card, that is funded with STEEM/SBD, and acts as a bridge between digital and legacy real world?

Just an FYI, we can do that right now. TradeQwik just treats SBD as USD at a rate of 1:1 we don't even have an SBD market, you deposit SBD and you're credited with a face value amount of USD.

You can withdraw to your card existing card, or we can issue you a card once we get enough orders to make it viable to order a batch.

We also run ATMs (albeit in Mexico) where you can buy and sell SBD, we may expand that network soon.

Sorry not trying to take over your thread with an ad, but everything you're talking about, are things we're working on right now. Follow @tradeqwik and @vivacoin for more details.
