It's a sign of the times: the next bitcoin mining difficulty update might be the largest drop this year.

The adjustment is projected to happen in the early hours of next Tuesday and could be between -8% and -7%, according to most estimates. Luxor placed it at -7.98%, Braiins at -7.9% and Bitrawr between -7.9% and -7.5%, at the time of publication. 

"The upcoming difficulty adjustment is tracking to be significantly negative, as hashprice levels hit resistance points due to mining profitability thresholds turning negative," said Ethan Vera, COO of Luxor, a bitcoin mining software company, which runs a mining pool.
