I know Dude came much later. remember when he did his prediction games and changed his name
Indeed. He seems to have obliterated all traces of his old name from Bitcointalk.
A quick search of BCT reveals only a single post referring to him as I remember him spelling it and mentioning ElDuderino in the same sentence.
Even a Google search only reveals a thread misspelling it with an extra "o". Lots of mentions of other people with the same surname with a single "o". Only the misspelled one refers to BCT.
I thought that maybe it was a name change and not a new account.
Maybe the Dude can clarify the matter without too much of a breach of opsec.
