Bitcoin testing key support level, altcoin open interest exceeds Bitcoin for the first time

The Bitfinex Alpha report shows that Bitcoin has been trading sideways in the range of $77100 to $81300 for the past 20 trading days, and the current price is close to the support level of the low point in the range. If it breaks through $81300, the above trading volume vacuum may push the price to $86500. The options market moved protection to contracts expiring on September 18th before the Federal Reserve's interest rate decision. Bitcoin's volatility has decreased, with all 29 major currencies rising last week, including Polkadot up 43% and Zcash up 42%. The open interest of altcoin perpetual contracts exceeded that of Bitcoin for the first time this week. (Source: Federal Reserve)
