After a slow start, blocks on the newly launched bitcoin cash blockchain are now being mined more frequently.

When the cryptocurrency originally split from the main bitcoin blockchain earlier this week, blocks were crawling in, with the first one taking about five hours to find and another taking nearly 13 hours. This came as no surprise to many, since bitcoin cash has much less mining power (with only a few groups, ViaBTC, Bitcoin.com and other unknowns securing the new blockchain).

But since blocks on the bitcoin blockchain are generated roughly every 10 minutes, some onlookers derided the new cryptocurrency for this initial roadblock, one that made it more difficult for users to send transactions or exchange bitcoin cash for other cryptocurrencies.

However, block speeds have since picked up a bit. Today, for example, there's been roughly one block per hour.

This change is directed by an automatic adjustment of the difficulty (a function that regulates how easy it is for miners to generate new cryptocurrency tokens). Bitcoin cash's difficulty has adjusted since it first broke off Tuesday, so miners are now having an easier time finding blocks.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

16:9 Image

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.

What to know:

  • KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
  • This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
  • Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
  • Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
  • Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
