Can I use Cold Cups for hot and cold drinks?

The answer is 'technically, yes', you can use KeepCup's Cold Cups for hot drinks. The straws are made from the same material as our plastic hot coffee cups so there's no issue with the material. However, drinking hot beverages from a straw should be done with an abundance of caution; Hot liquid delivered directly to the mouth through a straw can increase burn risk because it bypasses the cooling and mixing that happens when sipping from a cup edge.
