Bitcoin traders have set a new record for futures positions, with open interest surpassing $37.7 billion. This comes after spot bitcoin ETFs extended their net inflows streak to 18 days, also a record. 10x Research suggests that Bitcoin could surge to $83,000 if it moves above $72,000 to complete an inverted head-and-shoulders pattern. Health-care company Semler Scientific has announced that it is purchasing $17 million worth of BTC and preparing to raise $150 million so it can buy more.
