Hey guys,
I'm pretty new to the mining game (just started with a HF account on SHA256) and I like the idea of contributing to the network instead of just buying coin as an investment.
I have roughly $30k to invest and I would like to hear out your ideas, especially from people who have experience with different builds and cryptocurrencies.
As of now I was thinking of going through in January with 5 rigs consisting of 12 Sapphire RX580 8GB Limited Edition on an ASRock H110 mobo, each. My objective is to mine ETH and I'm counting with steady 30MH/s+.
Pitch in your ideas, do you think this is a good idea or is there a better way to build a rig and invest my $30k?
Thanks in advance

well, I think I will make slightly different
1. I'd go for some rx570 4g (or 8GB for 15-20$ more) - maybe 2 rigs with them - they will be mining crytpnight coins, there no need to buy RX 580 which is more expencive and have almost same performance.
2. Then 3 rigs with RX580 for ETH or dual mining
3. Then I'd take 2 rigs with NV1070ti - for other coins that loves nvidia cards, btx, zcoin, neoscrypt and others
