SINGAPORE - Bitcoin hit a two-year high on Tuesday on signs of large players buying the cryptocurrency, while smaller rival ether topped $3,200 for the first time since 2022.

Bitcoin has rallied more than 10 percent 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 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.

Bitcoin rose as far as $57,036 in the Asian morning its highest since late 2021. Ether rose as far as $3,275, its highest since April 2022.
