1. yes there is a bright future for btc. in 2010, the price of btc was very very low, less than 40$, while today the price has increased upto 600$. btc has a great potential and it can make you very rich even if you just hold it and sell at the right time unlike fiat.
2. btc can be used in many online shops to buy electronics and other goods. but we still have to wait for the day when btc can be used in most of the physical shops as well. and believe, we dont have to wait too long for that day to come.
