@TMag123 I started in February with 5TB, then quickly went to 17TB then 29TB. After a few externals I was right around 50 TB and mined approximately 50,000 coins in a month. I'm now up to 72TB and will finish plotting another 8TB external tonight. I've one more 8TB after that, then I need to go buy a couple more. My goal is 100+TB by July.

Just keep adding a bit as you can afford it. It's kinda cool to see you earnings increase as you add more drives...especially as the coin value goes up!

Good luck!
