Bitcoin has rallied more than 10% in two sessions, helped by a Monday disclosure from crypto investor and software firm MicroStrategy that it had recently purchased about 3,000 bitcoins for an outlay of $155 million.

The original and largest cryptocurrency by market value has also been buoyed recently by the approval of bitcoin-owning exchange-traded funds (ETFs) in the United States. On Monday, trading volumes in several of the funds spiked, and crypto-linked firms rallied too, in contrast to nervous broader markets.
