My question is: How can you tell from the public key that the public key is multi-bit?
How can we determine the bit length of a public key

for example :  19zK7RvpE7UE7nDaRtLcTAw98tyyYr8Pz7
You cannot. No one can. We know the bits of the addresses and public keys (every 5th) for the challenges because of the challenge itself and from words the creator once said.

But for a random address or public key, no one can say what bit range it is in.
