In fact, 0.10.2 is not originally announced Riecoin, it's something else.
Only the difficulty and the reward (subsidy) calculations are being updated.
I don't know why Gatra did not just fork his coin to make a new one.
Instead, he preferred to throw 30% of users and change the protocol.
If you allow him to do this who will stop him if he will change it harder?
This is very sad when you should be excited about the superblocks for k-tuple prime world records breaking. If you had followed the Riecoin development from the beginning then you should know moving forward by the hardfork is good. And it's a must from certain research prosepctives. I don't think it's in Gatra's intention to abandon your so-called 30% stackholders.
You and the other 30% have absolutely nothing to lose but everything to gain from v0.10.2.
Brothers. Sisters. Please update your wallet to v0.10.2
