Slowly society will see how physical cash gets erradicated, and BTC will be the leading way to move money.
I agree!

physical wallets with cash in them will be a thing of the past!
Yes as the world becomes and more global and the ease of making transactions between nations a single payment form without a processor is king and especially when decentralized. These strengths will lead the charge and then it will seep into all transactions.
do you think payment intermediaries/third parties such as visa/mastercard will vanish? maybe big corporations and banks won't let bitcoin be accepted!
