Think little goals and expect little achievements. Think big goals and win big success. Don't fall behind. I am very confident in what bitcoin is showing up to today.
I think If blockchain is adjusted to our eveyday transaction, it will replace the bank as we know it. You can store unlimited amount of coins in your wallet and have some wallets at that time. Transactions will be end-to-end. No more atm or savings book. But still long before this happened.
Currently, companies that accept bitcoin transactions use Bitpay to convert bitcoins into money. So still down to the money. Bitcoin will not replace the money for the transaction in the near future.
For banking, the future of bitcoin is actually a blockchain technology. Coins may change in the future but blockchain remains a major driving force.
