Bitcoin is nothing but a money transfer system and not even easy to use compared to Paypal Forget the mass adoption, even 50$ BTC is overpriced when you think about how useful it is
Even if Bitcoin is ill-suited for instant money transfer, there are a few things that make it (and some alt) unique :
- you are the owner of your coins as long as nobody else knows your private key (so avoid web wallets) ;
- you don't need to trust anybody to store your money ;
- you don't need to be accepted by financial system to receive coins ;
- total amount is capped, and inflation controled meanwhile ;
- there is a good level of anonymity if you stay in legit economy.
So for a value storage system, Bitcoin is a must.
For daily expense, I think we could transfer Bitcoin to a trusted intermediary (bank, Paypal) then use current system. Exposure is limited as you keep owning most part of your coins in your wallet. This is the best of two worlds.
It is time to banking to change their business model.
