Have a question, What would be the approx profit if I put in 1btc? or .3btc?
Gigamining/Terramining bonds/contracts are are not for sale.
This is good news for those, who still have their coin but have not understood why mining "bonds" (especially perpetual and hashing speed related) are really bad investment for the bond holder aka YOU (and not for the guy who got the rig for free - bought with bondholders money).
There are multiple threads about mining "perpetual mining bonds" aka "turds", so I am not going in to details here.
If mining
bond turd is Mh, Gh or Th based, you will get screwed when difficulty rises. You earn less and less income, "bond" price will keep falling so you also lose your principal. If this crap is "perpetual", the issuer has no obligation to buy back the bonds any time soon so you have no guarantee of getting back any of your invested coin.
Confused? Read up on what bonds actually are and why owning equity is different form owning debt.
PS! If calculations like 1-0.001+0.0001 give you a nose bleeds, you need to leave this subforum. FAST!

As I have said before, just as in buying mining hardware for mining, reinvestment is required to maintain gains. The problem with Terramining (as opposed to perpetual/traded turds) is that you cannot reinvest by buying shares from Giga or anyone. once Terramining is in full swing each week/months/etc... dividend will go down. No matter how much money you want to throw at Giga or people with bonds/contracts your dividends will drop and Terramining will end.
