EURGBP - Fade the Breakout for huge Risk:Reward?

EURGBP just broke the Trendline, but it does not seem to be that powerful.
On the H1-Chart we can see some rejection in the area of the recent highs at the top of a Channel.
This trade might be very risky, but the Risk:Reward-Ratio could be worth it, because a False Breakout is likely to cause a big move in the other direction.
