are there any other coins that have a halving coming or who just have halvings like ltc and btc?
LTC halving is pretty new to me. I know BTC halved to BCH, but not too sure if LTC also halved. Maybe Ethereum will halve too in future to Constantinople.
Halving means when block reward drop by half as of now miner can earn 12.5 every block when halving occur it will drop to 6.25
BCH is what they called fork its a altcoin generated in bitcoin blockchain
