Eran-
The sheer volume of point cloud data, as Howard says, makes it very hard to display in a traditional web browser system, e.g. OpenLayers fed by JSON. You'll need to find a way to reduce the point count in a smart way - like feeding out a LOD (level of detail) algorithm.
Two or three years ago, people started looking for good ways to do this. There might be an open source solution by now, but it would require something more heavyweight than just OpenLayers.

You could try using PDAL to export point cloud data to GeoJSON (using drivers.text.writer) and importing that into an OpenLayers map in some way. You are very likely to overwhelm any browser, however, with any significant amount of point cloud data.
