Still, saying that you don't accept the concept of trust is a weird statement, especially given that the next sentence ("I don't trust them") uses it ;)

I think you still trust those services with your money in the same manner you trust classic banks - no real difference here, both can be used just for transfers and not keeping anything with them. Except for with banks it's really tiresome and inconvenient to load on demand and with Bitcoin it's nearly a one-tap experience.
