new to Bitcoin, something i don't get !

[aliitp]

thank you all guys, I read ALL of you replies and am coming to realize more that BTC is not just a broken concept or something that will fade soon as it will depends on demand/supply just like gold or maybe other currencies, but here is my question, why is it not profitable to mine anymore say starting with 1 TH and go all the way up from there ? (why won't i get ROI on the hardware cost i spent) and do the big players in BTC get ROI for the hardware cost,electricity bills and DC costs ??...

and btw I was referring to this calculator:
http://dustcoin.com/

Thanks again,

It's not that you won't ROI because you probably could still ROI. It's how fast you gonna ROI with Bitcoin value being so low. Ideally you would want to get your initial investment back as soon as possible because the longer it takes the riskier it is. Of course it's always going to be a bit of a gamble as Bitcoin value can go up or down at any time.

so is it or is it not a good idea to get a 1 TH/sec miner for now (probably antminer) and grow up my collection of miners from that point ?...
and what is the cheapest 1 TH/sec miners out there ??..

am currently playing with those 2 GH/sec baby USB miners as am a beginner, a waste of 60 $ spent !~
