I want to maintain maybe 3 to 5 validators. But can I get my burned coins back since there will be no block reward?

RC Test

(1) The purpose of RC test is to further verify the semux software and clear potential bugs;

(2) To encourage participation, validators are rewarded 1 SEM per block;

(3) All coins you minted/received during the test will be transferred to our main test 1:1 when we officially launch, which is expected in early 2018;

(4) After RC test, the chain data will be dropped and all balances (plus delegate registration refund) shall be carried over;

(5) Please check our official ANN page and discord channel at a regular basis for updates.
