Could a giant solar flare take out all cryptocurrency?

What is a solar flare you might ask?

A solar flare is when the sun releases radioactive energy like you see above.

It is basically the same as an EMP, and some say that if one large enough is released in the direction of the Earth that it could wipe out the entire electrical grid leaving us in a world that looks more like the 1700's.

Now what I am concerned about is what if something like this were to happen worldwide..

Could a giant solar flare take out all Cryptocurrency?

If all electrical systems were wiped out at once by a giant solar flare would cryptocurrency still exist?

I would hope that heavily invested miners have already taken appropriate precautions to protect themselves against risks like this..

When I see movies like "Red Dawn" and "Ameriggedon"where they were threatened and even attacked with an EMP it got me to thinking of how I could protect my family, and my emergency supplies?

(Like cell phones, radio, walkie talkies, solar chargers, battery packs, and other electrical equipment)

And then I came across tutorials for "EMP Proof" safes and storages..

And even EMP proof bags!

So as we can see there is obviously ways to protect our electrical equipment, and from my research I have seen that "galvanized steel" helps protect against this as well, and also having cardboard lining the inside.

We just need to focus on upgrading the global grid for the future digital community, and make sure we are always prepared for all possibilities!
