I think the majority of those who invest in this market is rich and the only goal is to make money. OK, there is surely excitement of new technology, but now it is just the opportunity market.
rich people can invest with large capital and for those who have small capital, they only invest small capital.
they can get rich by investing because the profits they earn are very large, but they all need a process to get rich.
they can also be poor because of insurmountable risks.
