I will revise your subject.

Bitcoin is more than a currency or security it'sor scarcity, but are decentralized, secure and private!

If Bitcoin didn't have one of three I mentioned above, I doubt Bitcoin can grow as high as now since there's a weakness in Bitcoin and it would make people to not completely trust in Bitcoin.

Before preaching about money and bitcoin you should really study Bitcoin more.
The circulating supply of Bitcoin is always increasing and will do so for a long time from now, the amount will not shrink (unless major accidents) for decades to go.

Second, scarcity doesn't mean something has value, there are thousands of tokens/coinsaltcoinsforks that are also "scarce" but this doesn't mean they have value, it would be enough to look how the 21 million forks of Bitcoin have the same supply and issuance and BCH is $500 while BSV $60.
One needs utility before scarcity to have some value!

You have started a good topic, this factor/feature of BTC definitely needs more hype. As in the long run scarcity of BTC is the main factor that plays an important role in driving its price in a positive trend. Otherwise, if it would be normal fiat then there would be a need of centralized authority, that could implement Interest rates, or pegging it with limited supply of commodity like gold. That would be against the context of BTC.

Therefore I am glad that Satoshi put scarcity factor in it. Besides BTC I was confused why you said money need to be scarce, as I do understand that to save the value over time just like BTC is doing, but till now I did not saw a single country that have this feature of scarcity directly implemented in there currency although they do adopt other option to limit the circulation or printing of money, like increasing the interest rates, which stops people to borrow more money thus lesser printing and circulation, there might be other ways too, like open market etc.

Definitely bro I agree with you that if Bitcoin doesn't have any of these things So people will not trust on Bitcoin.
 
Decentralization, Sscarcity are the two important factors, which I think make Bitcoin promising to the world. Scarcity's greatest quality is that it influences the store of value, which also depends on decentralization. Despite these two qualities, they exist within Bitcoin. So I agree with you that if these two factors were not present in Bitcoin, people would not trust it as much as they do because of the lack of a value store and the lack of a decentralized ecosystem, that is, without scarcity and decentralization functions, Bitcoin would be considered a lay coin.

You must use correct term.

Supply is a confusing term. You can use Total supply or Circulating supply. The total supply, that is implied in your post, is capped at 21 million bitcoins. The circulating supply will increase and after four halvings so far, the curve for circulating supply will increase slightly in future years.

How is the 21 Million Bitcoin Cap Defined and Enforced?

You can use these available charts.

That's right , we need a combination of decentralization and scarcity to create value for bitcoin , without one of the two bitcoins would not be as attractive as they are today. But I value bitcoin's decentralization more than any of its advantages because no other asset is as decentralized as bitcoin, and that's what we've been looking for for a long time. Scarcity is important but is useless if not combined with decentralization. Because creating an asset with a scarce supply is not so difficult, but creating a decentralized asset like bitcoin is not easy and so far only bitcoin is unique.

Thank you for this information, you are very correct, I thought I learnt something important and wanted to share it with everyone but I did not get the information correctly. I always have an open mind to learn and get corrected because it will help me become a better person. I have looked at it again, scarcity has no effect when there is no utility for the product. An item that people do not want would not have value in spite of it being scarce and the examples of Bitcoin forks makes the point more clear. I did some research on the coins you mentioned and they are trading below Bitcoin in spite of their founders claiming that the altcoins are more Bitcoin than the actual Bitcoin. I see people are just greedy and want to take all the credit for Bitcoin success meanwhile the real founder born rounders are running away from all the attention and in the hiding.
