BGIN BLOCKCHAIN LIMITED , a digital asset technology company specializing in proprietary cryptocurrency mining technologies and the manufacturing of cryptocurrency mining hardware, revealed its “PortableBTC” commemorative prototype miner at Bitcoin 2026, the world’s largest BTC industry conference, held April 27–29 in Las Vegas. The prototype commemorates the Company’s entry into Bitcoin mining hardware development and its exploration of consumer-oriented mining products in line with BGIN’s “Crypto for All” vision.

BGIN’s Chief Corporate Development Officer, Rezwan Mirza, also participated in a discussion panel at the conference: “Lord of the Rigs: The Future of Mining Hardware.” He shared the stage with executives from across the Bitcoin mining industry and they discussed their views on the outlook for mining machines. During the panel, Mr. Mirza discussed how Bitcoin mining hardware competition is increasingly being shaped by broader full-stack capability, including ASIC design, machine manufacturing, operational efficiency, and power infrastructure.

BGIN’s PortableBTC prototype is powered by its BT1 chip. This commemorative unit marks the beginning of ICERIVER's Bitcoin mining hardware journey — from initial chip verification through system validation — and serves as a tangible milestone in the Company’s ongoing Bitcoin mining hardware development. The portable miner is a non-commercial piece — not for sale and not representative of any future production model in design, performance, or specifications.

“The PortableBTC prototype represents an early, tangible milestone in our Bitcoin mining hardware development journey and reflects our vision of making Bitcoin mining more accessible,” said Mr. Mirza. “As demonstrated by our seven consecutive successful tape-outs, we believe our ASIC execution capabilities provide a strong foundation for exploring consumer-oriented Bitcoin mining products. At the same time, we believe the industry is moving toward broader full-stack capability, where ASIC design, machine manufacturing, operational efficiency, and power infrastructure all play important roles.”
