Marco Streng, CEO of Genesis Mining, appeared on a panel discussion with Bitcoin developer Matt Corallo and Braiins CEO Jan Čapek at the recent Mining Disrupt conference. Streng noted concern regarding current levels of mining centralization. Streng specifically noted the advantage large scale miners have over small-scale miners as an issue. Corallo did not share the same concern but did note high levels of centralization in mining pools as a problem. Such problems are being tackled by Braiins as they announced a new mining protocol at the conference.
