If I know, they dont avoid bitcoin, they just dont believe in using it. it is true that bitcoin is easier when used for international transactions, it doesnt take long time. but people who dont know bitcoin, just think its a scam because what they believe is ordinary money. I have also experienced this, they underestimate me and underestimate bitcoin. they just lack education about bitcoin, if they understand how it works, maybe they will want to use bitcoin. it just takes more time to introduce bitcoin to many people.
