I think the Bitcoin price will increase over the next few years and be widely used by many countries. But I do not recommend using it to replace the money. If done too well, the criminals will use it to do money laundering.
Maybe the market price increase will happen for more years and for now the trend for bitcoin market price is in 20K USD as the highest crypto market price for bitcoin and stabilize on 6K-7K USD in the crypto market the same as with the next 3 years. And it will going to go more increase in the next few years.
