Bitcoin is already too expensive and definitely a giant bubble, not question about that. I'm looking at Mycelium wallet and just can't believe that "normal" transaction fee is 16.89 USD/byte?! Add in/out fees (for example ATM fees 6%+, LocalBitcoin premium approx. 7%, bank wire at exchanges approx. min $20) When I started using BTC it was free to send them, after that it was symbolic, now... it's not even competitive to classic payment systems.
