The price of bitcoin rose close to 10% this week, pushing higher as bullish market sentiment and low liquidity created an ideal environment for gains.
The digital currency enjoyed notable increases during the week, surpassing $600 on Sunday, 4th September, while largely avoiding any significant pullbacks or corrections.
Sentiment is so strong "players are not willing to bet against the rise of BTC/USD," according to Petar Zivkovkski, director of operations for Whaleclub.
