Vancouver, British Columbia--(Newsfile Corp. - September 13, 2021) - HIVE Blockchain Technologies Ltd. (TSXV: HIVE) (NASDAQ: HVBT) (FSE: HBF) (the "Company" or "HIVE") is pleased to announce provide its investors with an update on its data center construction in New Brunswick and that its Nasdaq tricker will be changing to "HIVE".

Expansion Update

Construction is in full throttle with our Canadian expansion which will enable HIVE to deploy an additional 20MW of green and clean Bitcoin mining before the end of calendar 2021, with an additional 20MW on schedule to come online within first quarter of calendar 2022. We expect this expansion to add over 900 Petahash per second to our Bitcoin production and enable HIVE to HODL more virgin coins.

Nasdaq Ticker

HIVE is very pleased to announce that effective Tuesday September 14, 2021, on the Nasdaq's Capital Markets Exchange that the Company's ticker will be changing from "HVBT" to "HIVE". "I am thrilled that we will make it much easier for Hive Blockchain technology investors and traders in both Canada and the US to have only one ticker. We are very thankful to NASDAQ in assisting us with acquiring the original symbol "HIVE" that relates to our name. This is important in branding and positioning our name in the minds and hearts of investors and traders as the first crypto mining company and only mining with green energy," said Mr. Frank Holmes, Executive Chairman of HIVE.

About HIVE Blockchain Technologies Ltd.

HIVE Blockchain Technologies Ltd. went public in 2017 as the first cryptocurrency mining company with a green energy and ESG strategy.

HIVE is a growth-oriented technology stock in the emergent blockchain industry. As a company whose shares trade on a major stock exchange, we are building a bridge between the digital currency and blockchain sector and traditional capital markets. HIVE owns state-of-the-art, green energy-powered data centre facilities in Canada, Sweden, and Iceland, where we source only green energy to mine on the cloud and HODL both Ethereum and Bitcoin. Since the beginning of 2021, HIVE has held in secure storage the majority of its ETH and BTC coin mining rewards. Our shares provide investors with exposure to the operating margins of digital currency mining, as well as a portfolio of cryptocurrencies such as ETH and BTC. Because HIVE also owns hard assets such as data centers and advanced multi-use servers, we believe our shares offer investors an attractive way to gain exposure to the cryptocurrency space. HIVE traded over 2 billion shares in 2020.
