I did a really shit job explaining to my GF the reasons why Bitcoin can only ever have 21 million coins.

Anyone got a simple, succinct explanation for this?

The goal is to have it easy enough that even she could use it to explain the supply cap to people.

ā€œBecause I say soā€ But seriously, it’s true. Your own node validates the rules, including the limit. By running your own node, you declare the rules you’re willing to accept.

It’s like adding a new constant to the International System of Units (7 are defined for meter, luminosity, etc.). Satoshi decided that he needed to define a constant for overall monetary value, so he decided on 21m bitcoin. Gradually, this will become the 8th constant of the International System ...

If I give you 50 milkbones each week, but halve this number every week. Eventually that weekly milkbone allowance will fall to 0. The number of milkbones you will receive was set up front, when I gave you the allowance, the frequency, and the halving frequency.

I’ve found it easier to tell people 21 million coins can and already has actually changed (eth, bcash, dogecoin, etc)… but in doing so, that creates a new ā€œblockchainā€. No need to go into detail of forks beyond that. The hard part for the people that change the supply is convincing people ...

The number of Bitcoins will always be less than 21 million. I can’t explain it any further than that. It’s really simple 🧔 if you do a bit of research, you can understand it.

The supply is limited to 21m by lines of code. Just like everything we use controlled by software (phones, internet, cars, coffee makers, electrical grids, etc) we don’t have to understand the code to use it. Because Bitcoin is so valuable, many software developers who do understand the code wat...

What specifically are you explaining? Why a hard cap at all, or why specifically 21 million as the hard cap? I’ll attempt to answer both: Why is a hard cap a good thing? The supply of any good can either be increasing, decreasing, or unchanging. Bitcoin is a good that’s defined and controlled b...

Because every time the number of coins gets 50% closer to 21 million, the rate of coin creation is cut in half. Imagine starting on a 10km hike at a rate of 10km/hour... after 30 minutes, you will have walked 5km. Then, you cut your rate in half to 5km/hour... so, after another 30 minutes, you wil...

Bitcoin supply is on a fixed schedule that was published when Bitcoin was created. That schedule caps the total supply at 21 million.

Because anytime someone would try creating bitcoin that has more coins, all the computers on the network will see it as invalid and they will ignore it. To all the computers it's immediately obvious if someone created such invalid/fake bitcoin that doesn't follow the rules.

Bitcoin is like a Birkin bag… They are valuable because not many exist and they are hard to hand make. If you mass produced the bags then the value of them goes down. Hermes may make a lot of money if they did this… but with bitcoin, there is no person or company in control. Therefore, th...

Imagine Bitcoin is a special treasure chest with 21 million gold coins inside. The person who made the chest put a magic lock on it that nobody can ever break. You can earn these coins by solving math puzzles ("mining"), but the magic lock has a rule: Every time 210,000 puzzles are solved, the rewa...

Bitcoin is ultimately computer code. It is hard-coded so that no more than 21 million coins can ever be created. True value in a currency is created by scarcity: when we had a gold standard, value was based upon the fact that gold is a rare metal. With Bitcoin, because the code says that no more t...

The current implementation of this current fork of "Bitcoin" has a supply cap but future forks of Bitcoin might not, and if that's what necessary for "Bitcoin" to grow, innovate, and stay relevant as a peer-to-peer electronic cash system then by all means so be it.

The total supply is an infinite series of halves. 1/2 + 1/4 + 1/8 + 1/16 ... On to infinity. Add all of them up and they'll never equal more than 1 whole. The whole supply of 21,000,000 can never be exceeded as the supply is generated as an infinite series of halves every 4 years. First four y...

The primary and possibly only purpose for a digital currency like bitcoin is to pay node operators in the native currency for securing the network through verification of transactions on the blockchain. There is no intrinsic value. There are two methods of payment: transaction fees, paid by the cu...

- If you take a very big bucket of sand and see this as the total supply of bitcoin that will ever be mined. - Then you start "mining" by taking a shovel of sand out of the bucket every 10 minutes. - This shoveling never stops. - The start you have a big shovel to take out the sand from the bucke...
