How much does it cost to destroy Bitcoin?

There has been a dreaded myth surrounding the so-called 51% PoW attacks against Bitcoin since inception. It is often believed that anyone able and willing to spend an amount equal to the “security budget” forever can destroy Bitcoin. That is, any evil government willing to spend about $60 million per day (matching miner’s revenue) would be able to destroy its $1.16 trillion current market capitalization. And worse, this figure may become lower and lower as halvings arrive if fee revenue is not able to take off consistently. Note that “forever” is just a credible threat, he will only need to spend that money for a period of time long enough until Bitcoin has been destroyed, which may be just a few weeks (at $420 million per week).

Here I will try to explain why the mentioned figure (currently 0.005% of bitcoin’s mcap per day) is not nearly enough to destroy Bitcoin, and show why it is unlikely that an attacker would carry such an ineffective attack for a long perio

Conda basics and best practices

Best practices

Don't install additional packages into the base environment
Give meaningful names to environments, e.g., PROJECT_NAME-env
Always specify package version numbers
Install all required packages in one command to reduce later conflicts
Install pip in each environment to avoid using the system default version
Always version control the environment.yml file

Assigning Static IP Addresses in WSL2

WSL2 uses Hyper-V for networking. The WSL2 network settings are ephemeral and configured on demand when any WSL2 instance is first started in a Windows session. The configuration is reset on each Windows restart and the IP addresses change each time. The Windows host creates a hidden switch named "WSL" and a network adapter named "WSL" (appears as "vEthernet (WSL)" in the "Network Connections" panel). The Ubuntu instance creates a corresponding network interface named "eth0".

Assigning static IP addresses to the network interfaces on the Windows host or the WSL2 Ubuntu instance enables support for the following scenarios:

	Preface:
	I have no idea if any of this is the "right" way of doing it. This is just how I got my unit working.
	Good luck.

	WARNING: Do not use a V1 Waveshare display module with a stock pwnagotchi! The pwnagotchi expects a V2 module, and may irreparably damage a V1 module!
	A V1 display module can work, but you must modify `waveshare.py` and `display.py` beforehand. For the time being, this is left as an exercise for the reader.
	If you have already burnt a V1 display, try disconnecting it from the Pi and leaving it overnight. This may rejuvenate the display somewhat, but it will likely still display signs of damage.

	Installation:
	1. `dd` Raspbian Lite to an SD card.
