Bitcoin is trading around $79,000. Looking at the liquidation heatmap, there is quite a bit of liquidity in the $81,000 to $81,800 range, and it seems to be acting as support. The upside is concentrated with shorts in the $88,000 to $91,500 zone.

In reading the market sentiment of cryptocurrencies, these densely populated areas on the heatmap are important, and if the price breaks above, that concentrated short zone is likely to become the target. For now, it's sideways, but which way it moves depends on this key point.
