Mr Adams, a Democrat, will in January become the second black mayor of the United States' most populous city.
He easily defeated Republican Curtis Sliwa, founder of the Guardian Angels civilian safety patrol, in Tuesday's election.
His post was a response to Miami Mayor Francis Suarez, who wrote in a Twitter message of his own that he would take his pay cheque in bitcoin.
Mr Suarez won re-election on Tuesday.
Mr Adams told Bloomberg Radio on Wednesday he wanted to create a New York City cryptocurrency and he would look at ways to entice crypto companies to invest in the city.
US media outlets Forbes and NBC News reported the New York City Department of Finance was yet to comment on whether Mr Adam's request to be paid in cryptocurrency would be approved.
