Braiins used to talk big about open source then they did a 180 and quietly closed their source code. They also use FPPS which lets them do shit like keep out of band fees for themselves w/o compensating the miners. I don't know if they have abused this power but nothing is stopping them.

DEMAND also recently announced they will launch with Sv2 support like the same day OCEAN went live and everyone collectively shrugged and started yelling about OCEAN. All the other pools are more or less the same: KYC & FPPS. More pools presenting more options is better, exactly like Luke said. 

 They JUST switched TODAY and it was market demand as the reason for the switch. I haven't even gotten a payout from their FPPS system yet. I would rather get a consistent payout. You would have thought the same if you were getting the wild payouts on their pool before. Braiins has had v2 for like over a year...  

 Who switched to what? 

 Braiins switched payout calculation. 

 They switched to FPPS from PPLNS due to market pressure because all other large miners uses FPPS. This is a move away from transparency. 

 Actually, @LeoWandersleb said it best. More pools, especially with low switching costs, is the big win. BTW with OCEAN you need to stick around for 8 blocks to get the full payout iirc. So the switching costs are not that low...
