Data from Cointelegraph Markets Pro and TradingView show that BTC prices weakened, hitting a low of $57,230 on Bitstamp - a level last seen on August 16th. Toward the end of the week, poor liquidity led to a dismal monthly close, and buyers were unable to prevent further subsequent losses. As a result, bitcoin fell 8.6 percent in August, below its average gain of 1.75 percent, according to monitoring resource CoinGlass. Its data likewise suggests that September was a historically underperforming month for BTC/USD, with average losses totaling 4.5%.
