which block number guys???
725

great instamine
745 now...
The ETH block time is 15 seconds. Did this clone change the blocktime?
It is hard to tell an instamine without a block explorer. I don't think this was intamined.
This coin however was hugely premined.
Mining will be ended when the holders of Shf vote so (at a minimum of 2M Shf). They decide how much of a premine it will be in %..
