A Middle-Aged Woman Trying to Understand Bitcoin | Episode 2

Mining Was Not What I Thought

When I first heard the word:

“Bitcoin mining”

I imagined something completely different.


Honestly,
I thought people were somehow digging hidden Bitcoin out of the internet.

Like digital treasure hunting.

Maybe some genius computer people solving secret puzzles underground.

I had no idea.


But apparently, Bitcoin mining is not really “digging” anything.

That shocked me.


The biggest surprise was this:

Mining is actually about verifying transactions.


For example:

Someone sends Bitcoin to someone else.

Then computers around the world start checking things like:

  • Does this person actually own the Bitcoin?
  • Are they trying to spend the same Bitcoin twice?
  • Is this transaction legitimate?

If everything checks out,
the transaction gets officially recorded.

That process is called mining.


At that moment,
Bitcoin stopped looking like “internet money” to me.

It started looking more like:

“A giant global accounting system.”


Then things became even stranger.

Apparently, miners around the world compete using massive computer calculations.

And whoever solves the calculation first wins.


That winner gets:

  • the right to add the next block
  • transaction fees
  • newly issued Bitcoin rewards

This is called the mining reward.


So basically:

Computers race each other,
burn huge amounts of electricity,
and the winner gets Bitcoin.

This honestly sounds half genius, half madness.


And here is another crazy part:

Most miners lose.


Imagine:

999 people use electricity and computing power.

1 person wins the reward.

The others get nothing.


That is why huge mining companies are now dominating the space.

Apparently, regular home computers can barely compete anymore.

There are even specialised mining machines now.

Some mining facilities look more like giant factories than computer rooms.


But individual people still participate too.

Many join something called a mining pool.


A mining pool is basically a group effort.

Everyone contributes computing power together.

If someone in the group wins,
the reward gets shared.

Honestly,
it reminded me of people buying lottery tickets together.


Then I learned something else:

Bitcoin mining uses enormous amounts of electricity.

And this became controversial very quickly in my brain.


At first I thought:

“Why does digital money need this much electricity?”

But apparently,
the electricity itself becomes part of the system’s trust.

Because miners must spend real-world resources to participate.

That makes cheating much harder.


Supporters say:

“That cost creates security.”

Critics say:

“This is terrible for the environment.”

Honestly?

I can understand both sides.


Then I discovered something even stranger.

Bhutan has reportedly been mining Bitcoin using hydroelectric power.

An actual country.

At that point, my brain completely disconnected.


This whole thing started feeling less like technology…

and more like:

  • economics
  • politics
  • energy systems
  • human psychology
  • future society

all mixed together.


And somehow,
this is only the beginning.

Next episode:

I learned that Bitcoin transactions are not instantly confirmed.

Apparently, your money can sit in something called “Pending.”

My brain also went pending.
