Bitcoin Cash is at risk of an attack of 51%

The Bitcoin Cash network lost 30% of hashrate after bitcoin halving - this makes it vulnerable to 51% attack, according to Yassin Elmanjra, analyst at ARK Invest.

“Bitcoin Cash is not looking healthy:

-Hashrate down 30% since halving (& only accounts for ~2% of SHA256 hash)
-Economic throughput at all time lows
-Fees are .05% of miner rev (<$100/day)
-Theoretical 51% attack costs <$10k/hr, ” Yassin tweeted.

He added that he was surprised why the capture of 51% of the cryptocurrency capacities has not yet been implemented. According to the crypto51 service, the cost of such an attack is $8,800 per hour.

Revenue for this period amounted to $9.4 million - for comparison, in Q4of 2019, the indicator reached $66.5 million. The company's expenses in the first quarter of 2020 exceeded $15 million, which is associated with a two-fold reduction in equipment prices. “The overall market situation since December last year until January had not been too good.

According to the F2Pool mining calculator, Canaan devices are significantly inferior in efficiency to the equipment of Bitmain and MicroBT.
