Hi,
In the above picture, it is quite clear that Bitcoin has crossed 6500$ mark again today. But it is down at 6459$ right now, but hopefully it will close above 6500$.
After hammer at very strong support zone, next day, a confirmation bullish candle signals that bulls are very strong at this level and they don't want Bitcoin to go below this level.
You can also see that Bitcoin has touched this level 3 times but was unable to break it. It shows that it is the bottom of Bitcoin now and this market can move higher to challenge its ever high.
