It's a little complicated
Official Chia pools are not available yet, you can expect to start in few weeks, but we have 2 options right now:
Mining solo, you need to have a good amount of HDDs to mine, you can check here
https://chiacalculator.com/According to calculator, to mine at least 2 XCH monthly, you need to have 100Tb with the total network space of 18 EiB, and everyday this number is increasing
Mining with Hpool, this is not the official pool, but you can mine here, and this is a calculator
https://hpoolchiacalculator.com/I don't know how much TB you have, but to make at least 1 withdraw a month 0.1XCH you need to have at least 10Tb
Now you can do your math to see if it's worth or not
And remember, these plots of mining solo you can use to mine with Hpool, but will not be usable for official pools
Network space are increasing at a huge pace, it's hard
