Mining Pool BTC.Top Briefly Controls Over 51% of Bitcoin Cash's Hashrate

BTC.Top, a popular cryptocurrency mining pool, has recently hit a high of 54% of Bitcoin Cash’s hashrate, before seeing it recede. According to some users the mining pool has just been going after profitability, although any pool having over 51% of the hashrate could be cause for concern.

According to data from Coin.Dance, BTC.Top managed to mine over 54% of the blocks on the Bitcoin Cash network for a brief period of time, before seeing its hashrate go down. At press time, data shows in the last 24-hour period it mined 47% of blocks on the network.

Having over 51% of a network’s hashrate is seen as negative by many, as it could allow the entity controlling the majority of, in this case Bitcoin Cash’s hashrate, to pull an attack on the blockchain and double-spend coins.

This essentially means every network participant is forced to trust the mining pool not to attack Bitcoin Cash. Notably, BTC.Top is believed to have recently thwarted an attack on the network that sought to steal coins someone sent to a Segregated Witness (SegWit) address on the Bitcoin blockchain.

As such, network participants seemingly trust the mining pool was only mining the most profitable cryptocurrency on the SHA-256 algorithm, and wasn’t trying to act maliciously. This, however, doesn’t mean it couldn’t.

Various cryptocurrencies have suffered 51% attacks in the crypto space’s short history, including Verge (XVG), Bitcoin Gold (BTG), and Ethereum Classic (ETC). ETC suffered one of the most notable attacks, as hackers compromised one of the most popular networks in the space to double-spend coins worth over $1.1 million.

While BTC.Top heavily mines Bitcoin Cash, it revealed back in November of last year, before the hard fork that created Bitcoin Satoshi’s Vision (BSV) occurred, that it was apolitical and would support the blockchain with the most hahspower.

At the time Jiang Zhouer, the Chinese cryptocurrency mining pool’s founder, revealed BTC.Top’s goal was to recover stability for Bitcoin Cash, which at the time was engaged in a “war” between two sides.

On BSV’s side there are also concerns about a potential 51% attack. As covered, CoinGeek has reached the necessary hashrate to attack the network more than once, but hasn’t done anything malicious.

Crypto Market Update: Focus on BTC, ETH, BCH, BNB, XMR, and DASH

This article provides a quick overview of how the crypto markets have been doing—with the focus on Bitcoin (BTC), Ether (ETH), Bitcoin Cash (BCH), Binance Coin (BNB), Monero (XMR), and Dash (DASH)—over the past 24-hour period.

Overall, September 17th is proving to be a bit of a mixed day, with 12 of the top 20 cryptocurrencies (by market cap) in the red at press time (around 06:25 UTC).

The bad news is that are still waiting for the launch of Bakkt's physically-delivered daily and monthly Bitcoin futures contracts. So, Bitcoin is still trading mostly sideways, hovering around the $10,300 mark. The good news is that the launch is expected to take place in less than one week (i.e. on September 23), as was confirmed by this tweet that Bakkt sent out on September 16:

ETH-USD

The Ether (ETH) price continues its upward movement toward the $200 mark, up another 2.24% in the past 24-hour period (making it up 4.32% in the past 7-day period). What may have helped the Bitcoin price yesterday (September 16) is the announcement by crypto payment processor BitPay that in the near future it will be possible for its customers to accept Ether payments for purchases of goods and services. Also, the BitPay wallet will support Ether.

Ethereum co-founder Vitalik Buterin had this to say about the news:

"It is exciting to see BitPay leading the way in integrating Ethereum into global payment systems. This truly opens up a new world of possibilities for the Ethereum ecosystem, and together we can continue to be a leading innovator for real world use cases for cryptocurrencies.

BCH-USD

On Monday (September 16), Bitcoin.com announced that it had entered into a strategic partnership with Taiwanese smartphone manufacturer HTC, as a result of which the Bitcoin.com wallet will come preinstalled on HTC's current and upcoming blockchain phones (Exodus 1 and Exodus 1s):

BNB-USD

Although BNB is currently in the red, this may change during the next several hours once all of the six mini announcements that Binance plans to make today have come out:

The first of the six announcements that Binance CEO Changpeng Zhao (aka "CZ") referred to is the addition of support for Cosmos (ATOM) to Binance's Margin Trading platform:

XMD-USD

OKEx Korea announced on Monday (September 16) that it intends to delist all five privacy coins it is currently supporting, i.e. XMR, DASH, ZEC, ZEN, and SBTC, due to concerns that these cryptocurrencies do not allow it to implement FATF's so-called "travel rule". 10 October 2019 is the date on which transaction (i.e. trading) support ends.

DASH-USD

Since OKEx Korea's delisting announcement mentioned DASH, you would expect it to be down today, just like XMR. However, it is not, and that is very likely due to the fact that today (September 17) is the day that trading in DASH is expected to start on Coinbase Pro on/after 09:00 PST (16:00 UTC) provided that there is sufficient liquidity.
