BTCUSD reached some support in the 60min chart. It may trigger some corrective gains towards the upper line (marked on the chart).
To attempt timing the long trade, wait for the price to break above the current hourly high or wait for an hourly close above the lower line (support).
The upper line (resistance) may provide a short entry in BTCUSD where the price may re-test the lower support (lower line).
The analysis is intentionally kept simple.
