Bitcoin has reached strong resistance on the weekly TF. The resistance line goes the whole way back to 2017. So it's very reliable. A strong move downwards is very likely!
Based on previous times this line was tested, Bitcoin could fall 50% or more. However, the 74000-75000 level looks like a good support level. This would be about a 30% drop which is still very significant.
I expect profit taking very soon and short sellers to come in. There could possibly even be global headline news to cause this drop.
Be very careful in buying near the tops. Trade with your brain and not emotions. This is only an idea and anything can happen, but it's a weekly chart and seems very reliable.
