Most companies and people who use Bitcoin create a new wallet for each transaction. This is also what most crypto security specialist advice.
That’s such a waste, one might think.
Why throw a perfectly good Bitcoin wallet after it has been used only once?
In normal life, we are taught to be frugal. Every resourse we have is limited and every piece of the item should be reused and then recycled.
But in tech things are different. They are indepletable, almost infinite.
There are 2¹⁶⁰ possible Bitcoin wallets. In simple number that is
Let’s imagine that every person (7,7 billion) living on earth would create 1 billion wallets per second, which is not even possible using today’s computers. It would take 436 billion times longer than our universe has existed (13,8 billion years) to use all possible Bitcoin wallets.
That’s how many there are.
Bitcoin wallets will never run out. Our solar system and galaxy will die sooner than we’ll be able to use all the possible addresses. Even if we use all our resources and energy to build supercomputers that will create Bitcoin wallets at an unthinkable pace.
Therefore don’t worry. You can use a new wallet for every transaction.
So far we have used 22 million Bitcoin wallets. Which is almost nothing compared to the total amount of them.
And if there’s still someone who think that someone will be able to hack his private key I have some news for you.
There are 2²⁵⁶ possible private keys.
That’s 79,228,162,514,264,337,593,543,950,336 times more than there are Bitcoin wallets. So everything you read above multiply by this number.
Same applies to quantum computing. The individuals who think that in the future it will be able to hack Bitcoin’s private key, really have no idea how difficult that really is.
Quantum computer would theoretically be 100 million times faster than our current computers. That’s pretty fast, but not fast enough.
It will take around 4x10⁵² years for today’s computer to crack Bitcoin private key. Divide this by 100 million and you get 4x10⁴⁴ years.
That’s is truly a lot faster, but still not fast enough.
