Santiment: The news that Joe Biden has withdrawn from Democratic representation in the upcoming U.S. elections led to an immediate minor panic-induced drop in cryptocurrency prices. Despite the wildly different circumstances, the news of an assassination attempt on Trump two weeks ago caused a similar price pattern. In the late hours of Sunday, prices quickly rebounded after the initial drop, and they are now quite volatile at the start of the week. Expect Biden's endorsement of Kamala Harris to signal that any news about her or other potential replacement candidates will become constant trending topics influencing cryptocurrencies. Regardless of your own interest (or indifference) in U.S. politics, the social volumes of these major topics continue to prove a fragile correlation with speculative cryptocurrency prices.
