What if you could delete an occurrence from happening in the cryoto-world, both past and current events making it that they don't happen or didn't happened. What would it be?
I rather not do any of that!
Time is the one thing you intend mess with as, this would be you rewriting the history of not just a single person but, a log of individuals who would have issues reconciling there memory to deleted events or lost times of there existence.
When it rains here, its shining some place else, though the sun might shine at a spot, the earth does rotate to ensure an even measure of shine on zones.
The sad events that might have occurred in the cryptospace was not all sad for everyone. There were those who benefited from these events and that to them was, a good decision and am saying this without giving any particular considerations to the scams and hacks.
The events is a learning opportunity and taking it out of existence is you as well taking off that experience.
