I think someone has already cracked the X10. Difficulty on Groestl coin has increased 4x in the last few days from 5630 to 19226.
i think you are right. could be baikal themselves mining with unsold units... would be typical of them to mine the new algos until profitability drops and then release them to the public saying "look, we weren't lying!"
Duh, it's rinse and repeat. Like how they were mining cryptonight themselves until it made chump change. Right now Groestl is HIGHLY profitable, so why would they release it right now? 2 new algos will be released when they turn into chump change too.
