I also think this is a relief rally after about 2 months or more of consistent price action within a range.
As we popularly reply those who troll technical analysis of Bitcoin, if it doesn't go down, it will go up!
We have seen a log period of bear market similar to what was experienced in the past ones, and demand for USDT has been going up. This indicate that things could be reversing, but unless a higher low and a corresponding higher high are formed, it's best to be cautious with your trades.
Some thing that's sure is that if you do dollar cost averaging at strong supports like $18k proved to be, you could make some sweet profits when there is a relief rally like this. No one knows the bottom too, so waiting for lower prices that may never come could have you fomoing if a bull run comes around unexpectedly.
