Bitcoin can only reduce crime rate in the society for the ones who knows how to read and write because someone who don't go to school can't just wake up one morning and start talking about Bitcoin. The important thing is anything that has positive also have negative... Bitcoin can reduce crime and can not also reduce crime.
Though you correct sha, as people need education to be able to understand and thrive in crypto but I just wan ask you weda, people wey no go school, no dey use bank? For our country both the educated and uneducated persons dey fit use phone, sometime our mama dem go call is to help dem dail person number or save number wey dem fit dey call. And small small dem fit do am by them selves. But talking about Bitcoin even if then no fit make trades and transactions by themselves dem fit call one of their trusted children to help dem dey make transactions. Majority of persons in this world are getting digitalized but the few wey no fit meet up, no problem, because no matter how people adopt reach, no be everybody go fit hold Bitcoin, some by choice while others Na by restriction.
