Interesting what happened with Bitcoin on Monday - the nearly five percent increase was apparently mainly short-covering, not really new buyers stepping in. That is an important difference. Short squeezes can quickly fall apart again if the volume decreases. I looked at the market data and it seems that traders closed their positions instead of genuine buying interest behind it. That also explains why the move doesn't seem so sustainable. Anyone still involved this week should keep an eye on it – with such dynamics, it can quickly go in the other direction.
