Hello, please can I mine grin with AntMiner V9?
You cannot. Antminer V9 does SHA256d hashing algorithm, which is not compatible with Grin.
Ok is it profitable to mine with macbook pro?
No, you would mine almost no grin with a MacBook Pro, and would end up losing money due to the cost of electricity.
If you want grin, the simplest plan is to buy it.
Thats a hard lol my friend
you can’t directly mine grin but still mine other one for which miner is made and exchange them with grin on exchange
