Hi,

this is my first post here on the forum.

I have read a lot about btc mining during the last weeks and did quite some research on hardware and return of invest calculations.

As a result I haven't found any mining hardware available at this time - be it new or used - that would generate a reasonable return of invest over any possible timespan.
Some ASIC miner specs may lead to a positive calculation if theses devices would be available today, but all of these devices have deferred delivery dates...

So my question to the experts here: Are my calculations correct?
Or is there any hardware available today - used or new - that I can buy now and that will generate some reasonable profit? (no matter if it's 500 or 5000$)

Thanks for your thoughts,
