For example: Whenever you walk into a store, ask if they accept BTC or cryptocurrency etc. ? Even if you know they don't. It primes the cashier or manager to better acknowledge the next customer who asks a question like this and also starts a conversation or beginning to something new.
What would be your idea?
In my own thought the easiest way to help grow bitcoin,is investing this kind of cryptocurrency, and promote its good outcome to some of your friend ,and relatives by educating them how bitcoin renew your life because bitcoin is a life saver.bitcoin is a good another source of income so by promoting this into your community is not to hard to explain to them because people now needs another kind of resources,to sustain there daily needs.
