There is a high probability that ETH/EUR will reach another all-time high within the next seven days. If we look at the daily chart, we can see how on December 15th there is a long lower shadow doji. The next few days after that, the price broke the resistance level at that moment, 630€ (marked with the orange horizontal line), and established a new all-time high at 737€, which is the current resistance level. The current price is at around 685€.
All in all, I expect at least a 10% rise
