If you are an expert in bitcoin trading, then tere are chances to make a living off bitcoin. Only with the signature campaign income no one can the lead a life even he is single. Bitcoin ecosystem still in the developing. So it would take more time to get living out of it.
Signature campaign income? You could get banned or the campaign could close down.
It would be foolish to depend on something as uncertain as signature campaigns
im quite agree, what people can buy with just 0.035 BTC or 15$ for a week?, its just very crazy to quit day job that guarantee my life just for signature campaign
