Dear Experts!!

Recently the supreme court of India lifter the RBI Ban on bitcoins in India. Now I want to start bitcoin or ethereum mining here, depending on your suggestions.. I thought of setting up a custom rig but then i decided on buying a miner from Bitmain and some other retailers, The cost of electricity per unit in my state is-- $0.091
The choices of rigs i have are-----

AntMiner T17+ $905

AntMiner S17+ $1565

AntMiner E3  $600  (for ethereum)


so, guys, any recommendations or suggestions??

if you guys can suggest a better "custom" build then please share it eith me, I'd be grateful to you all!!
My budget is around $1600 my main aim is to learn the basics of mining and try to recover the money i will invest in this project/new hobby in 9-10 months or a year from when I start.
