Re: What is the best way to unbank yourself using cryptocurrency?
You should trying getting a debit card that let's you exchange your bitcoins and other cryptocurrencies at a great rate and so you'll be able to practically make your payments with crypto at every merchant that accepts a VISA/MasterCard. Try using Wirex for example. 
You're not unbanking yourself as long you are using a 3rd party to process a payment. Unbanking means not to use a bank account, Visa/Mastercard/Discover/Amex, Paypal, etc.
The current state of crypto doesn't make it possible to be 100% unbanked because soon or later your funds will need to hit 1) your bank account 2) the 3rd party as I mentioned
