All crypto exchanges should do merkle-tree proof-of-reserves.
Banks run on fractional reserves.
Crypto exchanges should not.
@Binance will start to do proof-of-reserves soon. Full transparency.
One of my minor gripes with many mainstream media publications is how unwilling they are to link directly to primary sources. Often I have to go through many different articles and search keywords to find the original document.
Linking to the primary source should be the norm!
