How deep BTC will correct ?

The market structure changed from bullish to bearish with a lower high and a lower low.
For me it's still a valid count to see this as a wave 4 correction.

i'm laddering in on spot from 42k (the last horizontal range / order block)

Let's see how this will proceed this year or next year ;) .
If it goes to 28.6k i will use leverage.
