While money is finite, value (and therefore wealth) is not. Any time someone figures out a new use for something, that thing's value increases. Technological (not necessarily computer) advancements are constantly increasing the total amount of value in the world.
This is because it is a broader measure of the money supply in an economy than when compared with M1 – which only looks at money that is in the hands of the public.
M1: Currency in circulation plus overnight deposits. M2: M1 plus deposits with an agreed maturity up to two years plus deposits redeemable at a period of notice up to three months. M3: M2 plus repurchase agreements plus money market fund (MMF) shares/units, plus debt securities up to two years.
Money serves as the most efficient medium of exchange that eliminates the issue of the coincidence of wants commonly associated with barter, allowing individuals, companies and systems to transact with ease.
The components of the most liquid measures of the money supply, M0 and M1, all act as a medium of exchange in the economy, while the added components of M2 are used primarily as a store of value.

Taking a buy-and-hold position in Bitcoin five years ago would have delivered massive returns for investors. As of this writing, Bitcoin is up 962.3% over the period. That means that a $1,000 investment in the token made half a decade ago would now be worth more than $10,620.
And that's why the Oracle of Omaha doesn't own the asset. “If you told me you own all of the bitcoin in the world and you offered it to me for $25, I wouldn't take it because what would I do with it?” he asks. “I'd have to sell it back to you one way or another. It isn't going to do anything.”
Age in a Group: If you have a group of people and you want to know the middle age, you could find the median. For example, if you have ages 12, 14, 15, 16, and 48, the median age is 15. Player Performance: In sports like basketball or soccer, coaches might use the median to understand a player's typical performance.
The backup 2-median problem is a location problem to locate two facilities at vertices with the minimum expected cost where each facility may fail with a given probability. Once a facility fails, the other one takes full responsibility for the services. Here we assume that the facilities do not fail simultaneously.
