Bitcoin (BTC) showed signs of stability on Oct. 10 as "de-risking" took over ahead of the Wall Street open. BTC/USD reached $27,300 before reversing to trade near $27,700. Derivatives traders controlled the trajectory for the time being, with some market participants optimistic about Bitcoin's support. Altcoins, however, faced sell pressure, with Bitcoin's share of the overall crypto market cap hitting 51.35% on Oct. 9, its highest level since mid-July. To avoid going short BTC, Crypto Tony flagged $27,200 as the level to hold.
