I think the best way to spread adoption is incentive. I am a huge fan of bch and have preached it’s usefulness nonstop. Whenever I find an establishment that I really like, I try to sit down with the owner and discuss accepting bch, but more importantly I always offer them $20 as a gift for doing so. It is definitely not a small amount for me but I think it really seals the deal for most.
I’m saying this because I got a couple places now (did a local sandwich shop today!!) and the deciding point was after I offered this gift. I know some may think the owners will never cash out but that isn’t the point. I think this is good for bitcoin.
