Bitcoin is rare . Just only 4 million left to be mined. Is this the reason why , the price increase? Need to know your opinion too.
it is the law of supply and demand (
https://en.wikipedia.org/wiki/Supply_and_demand), it is not just supply, it is supply
anddemand. in other words having a limited supply won't lead to price rise, there needs to be an increasing demand for it too. bitcoin has that increasing demand which is increasing with more adoption.
to understand this better you can go to
https://coinmarketcap.com/all/views/all/ and sort the list based on circulating supply then use Ctrl+F to find bitcoin and then check the other coins that are near it which have the same circulating supply. you can clearly see just having that amount of supply doesn't make them valuable.
for instance there is a coin called "Monster Byte" with nearly 17 million supply which is currently worth $0.06
