Bitcoin is so costly on the off chance that it will be changed over to my nation's money it will cost hundred of thousands. Why bitcoin worth that much even its lone a digital money would someone be able to give me a thought.
The price is purely based on supply and demand. Price is rapidly increasing because supply is capped and only a little bit of supply is added each day, meanwhile demand surges rapidly. As long as more people buy than sell the price will go up. And yes in the next few years you should expect a Bitcoin to cost hundreds of thousands of dollars.
If you're asking why it is in demand. Well then you can research that. But basically the reasons are:
1. it allows people to securely store their money without a bank (plus obviously get much better interest than the 0.1% annual interest or whatever you get from a bank savings account) that you yourself control rather than the bank and through them the government being in control of your money. It basically is a replacement for the entire banking industry.
2. it offers borderless payments so that you can send any amount of money to anyone in the world quickly and cheaply and securely without involving banks and governments and the associated fees and long processing times. It basically is a replacement for the entire wire transfers/sending money industry and will be a replacement or at least competitor to credit card companies.
3. since supply is capped it acts as a store of value and a hedge against uncertain economic times just like Gold. It basically is a replacement for gold for the tech age.
Each of these 3 key features are HUGE and by themselves are worthy of a price far far higher than the current price. When you put all three together, well, that's why you have some people talking about future $1 million Bitcoin.
