it's no called luck , it depends on the amount of wallet/gridcoinresearchd clients online and their holdings and packed into " difficulty " as you see on the client screen just under " block ". you can use 1 of the sites to track or code an app or if you are lucky someone will share the current one many of us use to watch each block. maybe ill insert a screen shot with 25 blocks and the diff levels being low and spiking vs the 8.0-11.0 current values. Gridcoin caters to whales and tries to force the rest to use the pool... its a sham and you can earn more than 10grc for CBR as i see as high as 240 if you take advantage of what wasn't voted on for CBR but is there to feed the whales aka the people whom are forced onto us labeled " trusted community members " go figure. Gridcoin is DEAD why do you think the original creator just washed his hands of 80,000,000GRC after being pushed out of ongoing development. The value has tanked so far it's really not worth the text or social media wasted on it daily and the time it took to write this. btw , not new going on 2 1/2 years.
