Looking for opinion for a mining rig

Hey folks, I am building new mining rig right now and I am looking for an opinion on the setup. I have 20 x RX 5700 XT (10 ROG Strix and 10 Nitro+). What realistic income I should expect from this setup? I have the cards with modded bios so as far as I understood I could have around avg. 50MH/s per card. Which will end me with around 1000MH/s total. I've checked on cryptocompare that I will mine around - 1.80ETH/month I do not plan to sell anything mined at least for 1 year. My first question is: Are the numbers which I am looking at correct ? Second question: What do you think about the strategy to hold and sell within certain period? I understand that the price of ETH could be lower 1 year from now but it could be higher as well.

Also any recommendations for a mining pool? Currently I am considering using nanopool.

Here are some thoughts:

• https://whattomine.com/
• ETH will slowly move to PoS and your rig will be useless if you want to mine it
• you only have a profit after you pay the initial investment
• most times it's worth more to just buy the coin and hold
• your reward will not be constant. In time it will get lower and lower based on the hash difficulty and participants
