Why block 761 was generated 04/17/18 and block 762 04/27/18?

761 - http://80.211.196.242/block/000000d243686b4ee6f56b98b3883a6461a9b30eb6a988b40c31b657725c5b5d
762 - http://80.211.196.242/block/00000062253e05b2a28496fed80a7372e20da59f4ecf21096feaa54923b683c3(editado)

461 blocks with 12 rewards generated in private pool? first message in bitcointalk was 04/27/18

2 - 300 Block - 1 KEC per Block
301 - 21703 Block - 12 KEC per Block (MN-10.8 / POW-1.2)

5842 KEC was generated between block 1 and 761

Look whom receive from:
masternode -> http://80.211.196.242/address/KpQdHwgiap4xmLEHL58PneqfaB9LYzPtgr

miing -> http://80.211.196.242/address/KXxW7b2nx7fwUx8UG9dXN87dZBAt9Qgy5R

1000 KEC transfer to create 1 masternode from mining on day 04/28/18 comming from mining

In my point of view, you should airdrop this 5842 KEC to everyone here in Discord

Just remember that you already have premine:
if (nHeight == 0) return 360001 * COIN;
