Scarce Resource
One of the main reasons for Bitcoin's value is that the supply of Bitcoin is limited. 21 million bitcoins will be supplied over 18 million bitcoins have already been mined. Because the value of Bitcoin is determined by the ratio of supply and demand. Day by day the demand for BTC is increasing and the number of Bitcoin holders is increasing due to the growing population and the price is likely to increase in the future. Experts believe that competition between holders will increase the value of BTC in the future when the supply of Bitcoin reaches 21 million while mining Bitcoin will not.
Decentralised Network
Another important reason for BTC's value is that BTC is a fully decentralized networking system. Centralized network systems could be controlled by governments like traditional currencies or controlled by one or more institutions, individuals and groups. But since Bitcoin is a completely decentralized system, it cannot be controlled by the government, so Bitcoin is completely Freedom.
Store of Value/Not to be Inflation
Bitcoin works completely against inflation, especially since governments can't regulate it and cannot print it in a printing press like traditional paper money and therefore cannot increase its supply. So it doesn't get inflation like normal currency. Due to lack of inflation common people can't keep in purchasing power thus Bitcoin's value is maintained.
Bitcoin's Utility & Growing Globally Adoption
Bitcoin's value is maintained as it is exchangeable with various products and day by day various circles, famous people, institutions, countries are recognizing Bitcoin around the world. Moreover, various business organizations are accepting Bitcoin as a payment system for their business. Because Bitcoin is such a global revolution, its value will always remain.
You just made some clean good points here. Bitcoin has a good value and it keeps growing everyday till each and every single individual get hold of bitcoin in little fraction which would be of big monetary value then. To add to the list but few are as follows;
SecurityWith bitcoin, you can convert your huge amount of fiat and move about with it stored in your wallet and conveyed with your mobile or Android phone. Possibly stored in your safe without anybody noticing that you have your assets kept there. Instead of moving about with bullion vans carrying huge bulk of cash about which would definitely attracts eyes to you, you can convert to bitcoin and move with it and nobody knows you have or carrying such an amount with you till you get to your destination. All these I have mentioned above would take place without anyone noticing your identity which put you on the safe side and your identity would remain unknown.
Saves time and minimize stressBitcoin gained more value in time consumptions it averts. Going by the normal fiat transaction, if one would want to withdraw or make payment for services with involves huge bulk in cash amount, it would take the time of those involved to undergo some scrutiny by several agencies involved before clearance to do whatever you want to do with it, while conducting such huge transaction of such magnitude, you will have to pay for transaction fee very much higher than bitcoin but if you use bitcoin, the fee will be low and it would scale through very fast to the destination without any delay but in the other way, Fiat is not so. After passing through stress sending such amount of money, if the account receiving such huge bulk of cash has not received such before, they would need to undergo another interrogation before they have access to the funds. So you see the value attached to bitcoin.
There are lots of them which would be gradually revealing itself as time goes on.
