لماذا الهيليوم مفيد جدا؟

Why is Helium so highly valued and utilized? Could you explain the unique properties that make it stand out among other elements? I'm curious about its applications in various industries, such as medicine, science, and even party balloons. Is it simply because of its lightness or does it offer more than that? Could you elaborate on its chemical stability and how it contributes to its widespread use? I'm also interested in its role in the field of cryptocurrency and finance, if any. Overall, I'm eager to understand the full scope of Helium's usefulness and the reasons behind its popularity.
