To truly understand why we need Bitcoin it’s important to understand money itself.
What is money?
Why do we need it?
Why Bitcoin?
There’s many books written on these topics but let me try to break it down for you:
At the core of any economy are people who perform work that produces value for other people.
A farmer grows food for us to eat.
A painter creates art for us to enjoy.
A mechanic fixes our car so we can travel.
A teacher educates our children so they can prosper.
Without money the mechanic can only eat if the farmer needs his car fixed.
Each person needs to want what the other is producing at the same time.
A teacher only needs their car fixed so often but the mechanic needs his children educated all of the time.
In addition to having what each other wants at the same time, they need to value each thing roughly the same.
This is very difficult to do in practice.
How do you value fixing a car against a teacher educating children?
There’s not an easy way for them to trade.
Money solves this problem by having something that can store the value being created by the worker to use at a later time and in amounts that make sense.
So what should we use as money?
Well some things are obviously not good choices.
If we tried to use grains of sand as money it would definitely help us keep track of how much value each person has and let us use amounts that make sense.
However, there is so much sand all over the Earth that it is very easy for people to get sand for work they didn’t do.
If we tried to use something like cars for money we’d run into the problem that they are not easy to divide into the right amounts.
We’d also see that not all cars are the same and some people would value certain cars more than others.
We can start to see what makes good money.
Good money is divisible so we can use exactly how much we want at a time.
It is fungible meaning each unit of the money is no different than the other.
It is limited in supply in that people can’t just go find more of it without doing the work first. It’s easy to carry around.
We might settle on something like gold or other metal coins.
These can be melted down and divided into specific sizes.
Each coin can be made the same size and likeness.
If we pick the right metal there is fairly limited supply on Earth. Coins are also easy to carry around.
Metal coins are decent money and were historically used for these reasons.
One of the problems is that while it’s easy to carry around a small amount of coins it’s still difficult to carry, store, or move large quantities of these coins.
How can we make this easier?
Let’s introduce a trusted community member (e.g a bank) that will hold all of our coins and will give out paper money for each coin we store at the bank.
This paper money is much easier to store and carry around.
We can always redeem the paper at the bank for our coins, right?
This paper money appears to work well, for a while.
It introduces a big problem though.
There’s a single trusted entity that is both creating the paper and holding all the coins.
There’s nothing stopping them from creating more paper than coins they have.
If they do this slow enough then no one will notice.
They can create more paper and slowly give it to themselves, their friends, their family, and certain businesses.
Everyone close to them loves it.
When they see how easily they can print they quickly get addicted to it.
Before too long the people who think they are storing the value produced from all of their hard work in this paper money realize that the paper money is not getting them as much as it used to.
It seems to be losing purchasing power.
What once got the mechanic three bushels of corn from the farmer is now only getting him a single bushel.
The more paper that is printed the higher the prices of the goods and services go.
The more value the people doing the work are losing.
This is the problem Bitcoin solves.
It is similar to the metal coins in that it’s divisible, fungible, and limited in supply.
However, it doesn’t have the problem that metal coins have of being hard to carry, store, and transport in large quantities.
Bitcoin is digital money.
You can carry, store, and transport large amounts of it just as quickly and easily as you can small amounts.
It doesn’t need a trusted party or bank to hold it for you.
Everyone can hold and transact the value they produced without anyone else.
All of the value their hard work produces can safely be stored in Bitcoin without the worry of some bank or government inflating the supply.
The supply schedule is known in advance and has a fixed total supply.
It’s the best form of money to ever exist.
I hope this helped you understand a bit more about why we need Bitcoin.
This information is extremely important for the world to understand so please share this post if you found it informative.

I’m sure you’re aware that the main purpose of the lightning network is to help Bitcoin scale by enabling faster and cheaper payments.
Did you know it’s possible to use it to send arbitrary data along with a payment?
Why might you do that?
Should you?
Let me break it down 👇
Normally when you make a payment using the lightning network the receiver has to create an invoice for the specific amount and then get that invoice to you somehow.
You then instruct your wallet or node to pay that specific invoice and the money is routed to the recipient.
There’s a feature called ‘keysend’ that allows you to send money directly to a node's public key without an invoice.
This means instead of having to communicate with the recipient in order to send a payment you can now do so spontaneously as long as you have their public key.
Did you know that Bitcoin maintains a 10 min avg time between blocks regardless of the amount of hash power that on the network?
It’s possible because of a mechanism called the difficulty adjustment and it’s incredibly important to understand.
Let me break it down for you 👇
The difficulty refers to how hard it is for a miner to find a hash that would be considered a valid block on the network.
A higher difficulty translates to more hashes needing to be calculated on average whereas a lower difficulty means less hashes are needed on average.
If we recall from my previous thread on how mining works we know that a miner is hashing random values in search of an output that is less than some target.
When they find an input that produces an output below this target they are able to produce a block and claim the reward
You’ve done your homework on Bitcoin and are learning about Lightning or just set up a node. You aren’t sure how it works and are nervous about losing funds
What’s involved in backing up a lightning node?
I’ve been using lightning for years, let me break it down for you 👇
Your Bitcoin is in cold storage. You stamped your mnemonic into a piece of solid steel.
It won’t be destroyed in a flood, fire, or acid bath.
You can finally sleep at night knowing your Bitcoin are safe.
With Bitcoin covered, you are excited to experiment with Lightning.
You fully expect a similar security model when booting up your lightning node for the first time.
I’ll get a seed phrase and stamp it into another piece of steel.
Unfortunately, it won’t quite be as simple.
What makes lightning more difficult to backup and secure?
My thread about the security of 12 vs 24 word mnemonic phrases surfaced some good discussion and some confusion. To clarify it further it’s important to understand the answers to:
What is a seed?
How’s it different from a private key?
Let me further break it down for you 👇
A seed is a set of random data that is used as the starting point for wallets to generate an endless supply of public and private keys for you.
If someone has your seed they can use it to generate the private keys for ALL of the addresses you use and ever will use.
The mnemonic phrase is used as an easy way to remember and/or write down your seed.
So if someone gets your mnemonic phrase they can use it to get your seed and eventually all of your private keys.
Something bitcoiners can forget is that it is challenging for the avg person to realize modern, govt issued currencies are a social construct and not a force of nature.
The illusion of fiat is completely pervasive and is reinforced constantly from our very first allowance 👇
A helpful discussion to wake others up to the injustice of fiat comes from the “The bitcoin standard” by @saifedean.
By simply asking the question:
“what makes for a good form of money?”
the perception of our local fiat currency as inherent and necessary can be broken.
Ammous' discussion of hard vs easy money illustrates that currencies that have an unlimited supply become worthless in the long run but there is also the possibility to strategically and nefariously siphon off a society's value through intentional manipulation of currency supply.
