Yep! Congrats! For your first POW!
You should setup your machine for more than one miner (3 is good for start) so when the first get in the queue the other 2 continue to use your machines hashing power (so you will not see the hps drop again)
go to config.ini and make it like this:
witness = "hossary1"
witness = "hossary2"
witness = "hossary3"
miner = ["hossary1","5JodfhtgiodfshgksdhfglkhdfsklghfdkHYFgujghfuggfu75h"]
miner = ["hossary2","5JKJhfYujguitgYDErtwtUJ647hjfhhjfk5544HHvhhHFSooJFp"]
miner = ["hossary3","5JlkhfdfTUKIK64FGKK7645BKFgxgjgjkgHGHjhvDjfHvjhU6hj"]
You can create new private keys for your new witness/miners with the command:
suggest_brain_key
I have the same problem. Should I create more than 1 account ?
1 account == 1 witness ?
