Traders eye "sweep of lows" for BTC

Data from Cointelegraph Markets Pro and TradingView showed BTC/USD hitting $19,224 on Bitstamp during Asian trading, its lowest since June 19.

A lack of momentum on upticks combined with a failure to reclaim critical support at the 200-week moving average set the scene for fresh weakness on Bitcoin. The largest cryptocurrency thus dived to the support area defined a day prior by Cointelegraph contributor Michaël van de Poppe.

In fresh analysis on the day, meanwhile, traders toyed with the idea of a relief bounce towards $20,000.

“We're looking for a sweep of the lows and a reclaim before we consider longing because this is a very strong downtrend and we first want to see some strength,” trading platform Cryptop told Twitter followers in part of a new update.
