In a technology of less than 10 years, which solely rely on internet and money. The risk to take up the space was left in fewer individuals that believe they afford to lose some money. Later some people did that to compete with people from other technology. I believe younger people are still more in the space, it just need to increase.
Ofcourse, because these young individuals have no fear in and it's not afraid in trying. They experienced less downfall and more on success, because they are stronger than we expected.
