The thing is it isn't a hobby I started with a singular 1070 slowly worked my way up I have over 30 rigs now after using my earnings and invested into a right thing at the right time. Now me and my buddy who has about 20 rigs are about to rent out a small place really soon as he's expanding another 20 rigs. No longer a hobby buddy however I do not advice borrowing money for a business you can get messed up especially for cryptos.
