BT1: Bitfinex ChainSplit Token (CST)
“BT1” primarily refers to a ChainSplit Token (CST) launched by Bitfinex on October 4, 2017.The purpose of this token was to allow traders to speculate on the price of the “existing Bitcoin blockchain” (i.e., the original BTC chain) following the SegWit2x hard fork (which occurred at block 494784 on Bitcoin). Bitfinex named the SegWit2x version of Bitcoin “BT2.”
The SegWit2x hard fork ultimately failed to execute, rendering the BT1 token obsolete.As of this writing, the BT1 (CST) cryptocurrency has been labeled “inactive”; its real-time price, 24-hour trading volume, and current market capitalization are all displayed as $0, and its circulating supply is also 0. It ranks extremely low in the market, reflecting that it no longer holds any value or prospects as a cryptocurrency investment asset.
BT1: BGIN Bitcoin Mining ASIC Chip
Another important reference to “BT1” is a 4-nanometer Bitcoin mining ASIC chip developed by BGIN BLOCKCHAIN LIMITED (NASDAQ: BGIN). This is not a tradable cryptocurrency, but rather hardware technology used for Bitcoin mining.
- Technical Milestone: On March 17, 2026, BGIN announced that its first BT1 Bitcoin mining ASIC chip had successfully completed its initial tape-out, marking a significant milestone in the company’s Bitcoin mining chip project. Subsequently, the BT1 chip entered the system-level testing and production preparation phases.
- Pursuit of Energy Efficiency: BGIN has initiated early development of a next-generation advanced architecture aimed at achieving better energy efficiency to address the growing competition and energy consumption challenges in Bitcoin mining.
- Potential Applications: Reports indicate that IceRiver may have referenced the BT1 on May 29, 2026, and demonstrated a related prototype mining rig with a hash rate of approximately 400 GH/s, suggesting that the BT1 chip could be used in its small-scale mining rig products.
The investment value of the BT1 chip lies in its technological innovation and potential impact on future Bitcoin mining efficiency, rather than in the direct purchase of tokens. Investors should focus on BGIN’s stock performance and the commercialization prospects of its technology, rather than on the chip itself.
Is BT1 Coin Worth Investing In?
Overall, the investment value of “BT1” varies significantly depending on the specific entity it refers to:
- BT1 as a Bitfinex Chain Split Token (CST): Given its association with a completed and unsuccessful historical hard fork event, and the fact that it is currently inactive with zero price and trading volume, it has no investment value whatsoever.Investors should avoid confusion and verify the latest project information on specialized platforms such as Svmuu.
- BT1 as the mining ASIC chip from BGIN Bitcoin: This is not a “cryptocurrency” that can be invested in directly. Its value lies in its technological potential as advanced mining hardware.Interest in this field should be directed toward investing in shares of the development company BGIN BLOCKCHAIN LIMITED or related mining companies, rather than seeking to purchase a cryptocurrency named “BT1.”
Additionally, there is another cryptocurrency on the market called BitCoin ONE (BTCONE), but it is not the same entity as the “BT1” discussed in this article. Its price and market capitalization are also extremely low, so it should be treated with caution as well.
