That's a lot of dust (229), I wonder if there's a plan to at least manually try and consolidate all of that in stages?
The plan is to wait for the minimum mining fees to be reduced. We would pay too high a percentage of the value to move them. There was talk previously about reducing it from 1 Sat/byte to 0.1 Sats/byte. I personally think it is inevitable at some point when BTC price becomes much higher.
And if there's a plan to some day phase out legacy addresses or a way to retain old ones already given to users and give new ones only segwit.
No plans at the moment. More likely to implement Lightning Network for deposits first.
