Remove meaningless precision from your GeoJSON. If your coordinates go out to 7+ digits, you are probably misrepresenting your data. Most scenarios in which GeoJSON is useful (i.e. web-related applications) do not require survey-grade precision, and a higher value is placed on a compact file size. Trimming the precision of coordinates can greatly reduce file size, while removing the appearance of fake high precision. geojson is a valid GeoJSON object, and can be of type Point, LineString, Polygon, MultiPoint, MultiPolygon, MultiLineString, GeometryCollection, Feature, or FeatureCollection. If you are unsure whether or not your GeoJSON object is valid, you can run it through a linter such as geojsonhint.
