If someone discovers a free, unlimited energy source, launching a 51% attack would be just a matter of seconds. And that is exactly what has happened.
There is a sacred rock located in Ranmasu Uyana, Sri Lanka. You can check here: https://en.m.wikipedia.org/wiki/Ranmasu_Uyana
This rock is said to have the oldest carving in the world. Older than the pyramids. What is interesting about this rock is that it emits energy. Precisely, unlimited, free energy. This place is referred to as a Stargate.
You can use an EMF detector and check the electromotive force emitted by this rock. An EMF detector is used to measure the electrical action produced by a non-electrical source.
EMF detector will show even very small changes in energies. And if you take an EMF detector and measure the electromotive force produced by this rock, you can see that the EMF meter's needle immediately goes all the way to the other side, which means, there is very high energy emitted from this rock. Potentially unlimited and free energy. You can check the video here: https://youtu.be/B-W-nQOQdq8
This rock is guarded by a fence to protect people from the energy it emits. EMF detectors usually only show up to 5 Milligauss, but this rock emits a much higher level of magnetic flux. Potentially unlimited. A Stargate in simplest terms is a gate to the stars. And there is an infinite number of stars in the ever expanding universe. This rock (star gate) emits energy. Precisely, unlimited, free energy.
With the right resources, anyone can easily utilize this unlimited energy to launch a 51% attack on the Bitcoin network. The cost of launching such attack would be incredibly low. The energy emitted from this rock can be easily converted to electrical energy with the right resources.
Discovering an unlimited energy source is a breakthrough. A breakthrough like that would have a lot of ramifications; not only to Bitcoin network but also to every human being on planet earth. But, my focus is only on Bitcoin.
If anyone properly utilizes unlimited, free energy, he/she can easily launch a 51% attack on all PoW coins with very little cost.
This sacred rock is just one way of tapping into unlimited energy. There are so many other inventions and discoveries that can generate unlimited energy for very little cost and resources. All these discoveries are hidden from the public by the powers that be. And this is the biggest threat to Bitcoin and other PoW coins.
The Solution
PoW is a failure. PoS is a better system. With Ethereum 2.0, Ethereum is slowing moving to PoS. The threat of someone having massive amount of electrical power is eliminated in a PoS system. As soon as the news breaks out, Bitcoin price will plummet. PoS and Ethereum 2.0 is the future.
