If I buy this https://www.ebay.co.uk/itm/322914881110?...Tags=bu=bu
Will I get 150k monthly? 
Is that truth? or how does it work?

why would anyone sell you something that gives you 150k monthly for 2k
wrong section too

IF you mine bitcoin block you could get few thousands $$$$ but its hard to mine solo a block.

If I mine other block what would be my earning then?

You will get 150k monthly if you mine some bitcoins and keep them for years. Might as well just buy them though :)

you would be better off investing instead. Those ant miners take a lot in electricity even more than the gpu mining. You really should do more research OP bitcoin is incredibly hard to mine now because of the difficulty levels.
