I am inevitable

Your crypto-planet was on the brink of collapse.
I'm the one who stopped that.
Do you know what's hanppened since then?
The cryptocurrency born...
have known nothing but full bellies and clear skies.
It's a paradise.

You could not live with your own failure.
Where did that bring you?
Back to me.
I thought by eliminating half of crypto... the other half would would thrive.
But you've shown me... that's impossible.
And as long as there are those that remember what was...
there will always be those that are unable to accept what can be.
They will resist.

I'm thankful.
Because now...I know what I must do.
I will shred this crypto-world...down to its last atom.
And then...with the stones you've collected for me... create a new one...teeming with life...that knows not what it has lost...but only what it has been given.
A grateful crypto-world.
They'll never know it.
Because you won't be alive to tell them.
