I have some doubts.
For few previous years of almost dead dtc the huge amount of coins are concentrated in one hands.
F.e.
https://chainz.cryptoid.info/dtc/address.dws?61563.htm with 11 mln coins.
I see the stable ammount 14 dtc clients of very old version. Not 0.8.6. Not 0.8.5.
It is 0.8.3 !!! version.

May be it is the same persons.
I think it is very bad. Such big coins holders and old node holders prevent the people trust dtc and prevent the progress and development of dtc.
May be we need restart dtc blockchain from new origin block.
