I vote for design number #1 by iawgoM.
Great design
As far as the copying goes the only similarly is the number 5 which I believe is older than either design.
Your older design has a 5 inside a bitcoin logo which is very different.
+1
How can you patent number 5? The logo with 5 inside B is actually more clever but is inferior in details.
It's is about the concept to celebrate 5 years of bitcoin, which has been copied.
Not about how detailed a coin has been made
