but going directly with trading, gambling and mining as a first job is pure crazy
you will end up losing everything in the long term, if you have some luck at the beginning i could see this working if you are good at poker and trading
because they are based on skill, this is true for the long terms
I think you are unaware of the opportunities bitcoin has in store for people, there are many job opportunities on the internet related to bitcoin based on the skills. People can earn money researching and writing on bitcoins, trading and understanding running a business along with bitcoin, mining and being involved in the block chain, devs which work on crypocurrency, marketing other currencies, marketing online gambling and even being a part of it, etc.
yes, very few people have knowledge about how big the bitcoin market truly is, surely there will be many business opportunities when more than 500k people are using it everyday individually and they are active. There are traditional ways of earning btc like trading, mining and now there are new ways like campaigns, marketing faucets, etc. Its a huge market.
