On the developer's site it was indicated that the version v.0.15.X was a test version and all coins will not be accepted on version 1.0.0.0. When I started version 1.0.0.0 there were 0 coins, all the coins that were obtained earlier on the version of the wallet 0.15 (2500 ~) were marked as - generated but not accepted.
And v1 has another algoritm.
This is true. Both of these should be considered experimental and for testing purposes only. Relaunch of the v1.x variety is still pending.
