Roger Ver for a long period of time believed Craig Wright was Satoshi Nakamoto. (Together with Jihan and Craig, Ver ignited the blocksize wars advocating for an increased block size in an attempt to attack Bitcoin Core whilst being convinced a larger block size would eventually make Bitcoin a digital peer-to-peer cash).

It was only until Roger found out that Craig Wright (a.k.a. "Faketoshi") didn't know an extended pub key address contains its own checksum that Ver understood Craig couldn't possibly be Satoshi, the writer of the whitepaper and inventor of Bitcoin.
