When playing with some iceland tools which is
https://github.com/iceland2k14/kangaroo i got this speed on CPU
- [24894.64 TeraKeys/s][Kang 28672][Count 2^29.29/2^29.10][Elapsed 06s][Dead 1][RAM 53.4MB/46.0MB]
Is it good bad fake idk but like i know iceland tools are good
iceland2k14 is proprietary and all his tools contain backdoor
do not use iceland2k14 libraries unless you want to loose your keys or findings
good luck
Proof what you said of GTFO.
Iceland tools are 100% trusted.
About the speed of kangaroo from that tools is a calculated speed amore o less about the expected speed remember kangaroo it is a probabilistic algorithm and it can't give you exact speed only a near speed based on some math.
