bitcoin is still compllicated to avg user. I mean unless you keep btc in say coinbase, imagine asking a person not tech savy to use electrum or a hardware wallet. I mean its not that hard... but not as easy as coinbase.
People may not still understand coinbase if they don't know the use of bitcoin at all, some were just too lazy or already set their mind in their beliefs about bitcoin, like how other uses it in doing scam that makes other lose interest. Only those who are willing to learn and is looking for change in transactions, investments and finding alternatives will appreciate crypto especiall BTC. Time will come that it will be too popular and many will just regret not starting using it the first time they heard it.
