As per suchmoon I moved this to it's own thread.
A few mods to what you posted
1) Set the date to the 21st which is the day after the inauguration, technically it's not official till the swearing in ceremony on the 20th sometime.
2) We agree President to mean President that has been sworn in as President of the USA, not that they just declare themselves president or Trump still being president of Trump property development.
3) Self mod thread. More or less I post this, you agree or we go back and forth in public with the rules till we both agree then it's locked away till January, plenty of places to discuss it elsewhere.
I would be willing to bet you BTC0.001875 to win BTC0.015* with the following terms:
If Trump is President as of 12:01 PM Jan 21, 2021(one minute after his first term ends), I win the bet
If Biden is President as of 12:01 PM, Jan 21, 2021, you win the bet
If anyone else is President as of 12:01 PM, Jan 21, 2021, the bet is a draw
If Biden or Trump concedes, the bet is payable to the other party, however, the bet will not be final until 12:01 PM, Jan 20, 2021. This allows one party to concede, and end up becoming president (for example if they won a court case)
*for clarification, I am risking BTC0.001875 and you are risking BTC0.015
The logic behind the above terms is that Trump's legal strategy is not necessarily to win 270 electoral votes, it is to deny Biden from getting 270 votes. If the electoral college meets and there is no winner (neither candidate receives 270 votes), congress votes on the next president, with each state getting one vote.
The above offer will expire 24 hours from the date of this post if it has not been accepted.
