Testing altcoin reward halving - Help!
If your test coin source code has the same regtest mode as bitcoin, you can use that, it allows you to mine blocks instantly and it's a completely separate chain to the testnet or mainnet so it won't affect anyone else. You can run your coin with the -regtest argument, and then use the generate RPC to mine blocks and see how much reward you get. Note that in the source code, the regtest reward halving may be (and probably is) a different number of blocks to mainnet, this can be changed in chainparams.cpp
