Which is more important？Block chain technology or bitcoin

I think bitcoin is just an encrypted currency. We are not pursuing electronic money, but block chain technology. Many teams now issue tokens to develop blockchain technology. These tokens, unlike stocks, can give investors dividends. So what are investors doing to make money? I can't think of any value in these tokens. The result is that investors hold worthless tokens, and the team takes the money we invest. So can I think these teams are trying to defraud investors in the name of developing blockchain technology? If the development of blockchain technology requires a large amount of capital, why not raise money through crowdfunding legal tender and then giving shares to investors? This makes it possible for investors to get a share of the profits through blockchain technology.
