You can now buy and sell NuBits (dollar stable coin) and NuShares (investment style token for NuBits) at
http://blocktrades.us via our instant exchange mechanism. We only have limited supplies of both in our inventory at the current time, however.
You can also now deposit NuBits and NuShares into the BitShares webwallet to purchase BTS (other conversion types will also be possible after the next webwallet update) via our bridge.
