Trading is a messy business. It brings all feats of human nature to the forefront. This has nothing to do with cryptocurrency.

The solutions that cryptocurrencies bring, are not negatively affected by trading. Once this field grows bigger and matures, I expect a stable - even boring - market for major cryptocurrencies as the vast majority will not be involved in trading but simply holds and spends currency on a regular basis, leading to regular currency flows. A stable ocean as opposed to sinking paper money.
