If BLK here refers to BlackCoin, its all-time high in public market records was approximately $1.31, occurring in early January 2018; its all-time low was approximately $0.000612, occurring in March 2014. In late October 2026, the reference price for BLK was approximately $0.04.
What is BLK: Name and Project Positioning
In the cryptocurrency context, BLK often refers to BlackCoin, a peer-to-peer, decentralized Proof-of-Stake (PoS) asset launched in February 2014. The project is positioned as a fast, low-fee digital currency that is more energy-efficient than traditional Proof-of-Work. Developer Rat4 introduced it as one of the early PoS mechanism implementations, aiming to validate the stability and security of Proof-of-Stake consensus.
As the ticker BLK may correspond to different assets, this article discusses BlackCoin (BLK).
All-Time High: Approximately $1.31 in Early 2018
Public market platforms record BLK's all-time high at approximately $1.31, concentrated in early January 2018, with specific dates varying between January 6th or January 7th across different platforms. This high point is historical data and does not represent current price levels.
Early January 2018 was during the peak of the previous crypto market bull run, and early PoS assets generally experienced amplified price volatility. For readers, the all-time high serves more to understand the asset's volatility boundaries rather than to measure current liquidity or project activity.
All-Time Low: Approximately $0.000612 in Early Stages After Launch
BLK's all-time low was approximately $0.000612, occurring in March 2014, shortly after the project's launch. This price reflects an extremely low point for an early small-cap asset with insufficient liquidity and limited market awareness.
From the historical low in March 2014 to the historical high in early January 2018, the price magnitude significantly increased; however, after the high, it returned to around $0.04, indicating that the long-term price trajectory is not monotonic.
Current Price and Market Cap Discrepancies: Data Shows Significant Differences
In late October 2026, the reference price for BLK was approximately $0.04. Roughly calculating with a total supply of approximately 64.5 million BLK, this corresponds to a market capitalization of about $2.58 million. If calculated based on a circulating supply of approximately 60.8 million to 64.5 million, it corresponds to about $2.43 million to $2.58 million. Some platforms provide a market cap range of approximately $2.5 million to $2.9 million, which is higher than the direct calculation based on $0.04 and approximately 64.5 million supply, indicating that their price or supply figures may differ.
Different market data platforms show significant discrepancies in BLK's circulating supply and market capitalization: some display 0 or insufficient data, while others show approximately 60 million to 64.5 million. Such situations typically relate to supply definitions, verification status, trading pair listings, and liquidity statistics. When comparing market caps, readers should simultaneously check price, circulating supply, total supply, and data update times.
Trading Activity and Risk Warning
BLK is an early PoS asset, and its current availability on mainstream platforms is unconfirmed. Liquidity may be extremely low, so please verify independently before trading. This article does not constitute investment advice or trading guidance.
From a project perspective, BLK's technical positioning is Proof-of-Stake, fast transactions, and low fees; from market data, its historical price volatility is significant, and current statistical figures are inconsistent. For such low-liquidity assets, price figures are more susceptible to small transaction volumes, platform listing differences, and statistical methodologies.
