In some countries have pioneered plans to close Conventional Banks and replace them with Digital Bank using Bitcoin. In addition, many Bitcoin ATMs have been built that function almost the same as existing Fiat ATMs.
But in my opinion this is only one good side of Bitcoin. Actually the most popular crypto has a very poor performance when applied as a medium of exchange. This is basically caused by very high volatility, which makes it inconvenient and impractical if you have to specify items or services in Bitcoin with price changes that are too fast.

For example, in the morning, you can buy a laptop with only 1 BTC, but due to daily fluctuations (which can range up to 30% -40%), in the end you can no longer buy the laptop at the price of 1 BTC, because the price has changed to 1.4 BTC. Unlike the perspective value on the daily exchange rate between EUR and USD which only averaged 1% and a maximum of 3% only.
