I'm not convincing even before but I tell on how good bitcoin is. I'm not pushing my friends and even my relatives, I'm just telling them that bitcoin seems to be the future and start of waking up the world about decentralization. I'm aware of those possible scenarios that might happen if I will have a debate with non-believers, they love to mock bitcoin folks since they are also aware of the bulls and crashes that happened. I'm even more keen of focusing within my goal than arguing with any of them.
