I actually laugh when I read all the text contained on the link. Yes you can really form number 13 if you do tried out to separate it but talking about the thing this is the thing why banks letting bitcoin to exist because they know whos satoshi just on that number? Whats the sense? Two digit number cant reveal anything.
13 is an important number on freemasonry, anyway, no relationship is mentioned in the steemit post.
A exemple of this could be found in this
ImageThere are 13 leaves on the left olive branch with 13 berries.
13 stripes on the middle shield.
13 arrows on the right.
13 stars above the eagles head.
13 letters in the "E Pluribus Unum" on the ribbon.
13 letters in Annuit Coeptis.
There are 13 blocks top to bottom on the pyramid.
Fritz Springmeir in his The 13 Bloodlines says these 13 blocks represent the 13 Satanic family’s.
With a little research, you'll find that number is being used often to be just coincidence.
