While, two weeks ago, it was estimated that Bitcoin (BTC) mining difficulty might drop by 16%, it just went up 5.77 % today, as more miners turned their machines on in the past two weeks. (Updated at 09:10 UTC: the second paragraph has been updated.)
The mining difficulty (used as a measure for how hard it is to compete for mining rewards) now stands at 14.7 T, or almost at the level, it was in the second half of January, according to major Bitcoin mining pool BTC.com. In the next adjustment in two-weeks time, mining difficulty is expected to rise by 5.65% to 15.55 T. However, this forecast will change depending on changes in hashrate, the computational power of the Bitcoin network. Should it increase further, the mining difficulty will follow. Since March 26 it's up by around 10%.
