My rationale is that the weak point of Bitshares (as well as other DEX'es now) is a high risk of liquidation. Imagine at some point a big part of BitShares holder decides to liquidate their assets. I'm not saying that this will happen, but the risk is here. And this is a major problem of all stablecoins Tether, Bitshares, etc.

I just looked at the current trading volumes, and they really grew. Perhaps it is worth playing around with BTS with small amounts, especially since there is an opportunity to write a simple bot for trading on these charts.
