Bitcoin hit a two-week high today, reaching $28,452 before sliding slightly to its current trading price of $27,916. Market observers attribute this surge to the U.S. tentative debt ceiling deal that was reached at the end of the previous week. After months of impasse, the deal is a significant step toward averting a possible financial crisis in the U.S., which would see the nation defaulting on its debts due to a lack of funds.
