"Once again we"re seeing some real resilience in bitcoin, which at one stage was pushing $40,000," said Craig Erlam, senior market analyst at OANDA in London. Bitcoin was last down 0.2% at $43,108 . Blockchain data provider Glassnode, in its latest research note on Monday, pointed to the "relatively low utilization" of the bitcoin block-space," which can be both a bearish and bullish signal. It added that current transactions on bitcoin are at 175,000-200,000 per day, "which are similar to levels seen in the 2018 bear market." CoinShares data also showed ether products had the second most inflows last week at $29 million, as investors looked to further improvements in the Ethereum blockchain. Ether though on Monday was down 2.1% at $3,000.88 . Assets under management at Grayscale and Coinshares, the two largest digital asset managers, dipped last week to $38.016 billion and $3.671 billion, respectively, pressured by the decline in crypto prices following China"s regulations news on Friday.
