New York: Stocks linked to cryptocurrencies rallied on Wednesday as Bitcoin was headed for its biggest monthly gain since 2019.
Some cryptocurrency-linked stocks have quintupled since October end.
Shares such as those of Marathon Patent Group that have soared 444% in the last two months jumped 7.6% more in premarket trading.
Riot Blockchain Inc. was up 4.2% on Wednesday after surging 383% since October.
Bit Digital that soared 81% on Monday, rose 15% more in premarket.
Bitcoin itself vaulted above $28,000 on Wednesday to a record, gaining 40% in December alone.
While some view Bitcoin as a hedge against inflation and the weakness in the US dollar, others say it is too speculative for a safe haven.
