I seriously don't understand "bitcoin has no tech" argument. These people must be very priviledged and stationary if they never encountered issues with current banking systems. At some places transfering money at local level takes ages and international banking is almost always a complete an utter joke. I've been waiting for over a month for a new debit card from Revolut while using their highest subscription tier and that's supposed to be the new hip, cool kids bank. It often takes days to move money between countries - even miniscule amounts that should be immune. Even our debit cards are region locked and extremely confusing, your VISA doesn't work the same everywhere. It's just complete and utter chaos if your finances are just slight bit out of the norm. Even if bitcoin is not the holy grail - it's still extremely useful piece of technology for many of us.
