Again, I know nothing about this stuff but when one sees serious accusations it would be a good idea to see something more than calculations based on assumptions some of which are questionable.
The "assumptions" you mention were based on industry standard or prices prevailing at the time of calculation.
every business has its own secrets that give his owners a competitive advantage.
You can indeed postulate that Gain may have some mystery super mining equipment that gives them an edge over the competiton, despite there being no evidence or even claim of such.
Well, right now one BTC $832 which is $150 more than that or 22%. 10 days ago one BTC was $1051 which is 50% more than that number and year ago the price was $377 which is twice as less. From my point of view it is hard to predict anything with such volatility or build any solid conclusions.
If investment is made in Bitcoin and returns paid in Bitcoin then the dollar exchange rate is irrelevant apart from converting costs incurred in fiat, which is what I used it for.
Bitcoin mined ∝ hashrate, end of story.
We don't know what miners they are using for Bitcoin (that's if they mine at all), let's say Antminer S7.
2nd assumption
At that time, S7's were the most efficient miner available.
Their latter video of the Chinese farm contained clear images of S9's and subsequent calculations were based on Antminer's own specs for that machine.
We don't know what they pay for electricity either, let's say $0.06, reasonable to cheap.
3rd assumption
Electricity costs money, but even using zero as a price the promised return is unattainable.
Gain make no charge for maintenance costs, who pays for that?
Throughout, I have used best possible scenario in Gain's favor for my "assumptions".
It is not payout size that make a business ponzi but the way its finances get managed.
What makes a Ponzi is the use of later investors' money to pay promised returns to earlier ones.
If the only real business activity revenue into a scheme falls short of matching existing payment commitments, then every day that goes by increases unserviceable future debt obligations.
Based on these "assumptions", this description matches Gainbitcoin's business model.
I have no personal axe to grind with Mr. Bhardwaj or anyone else, but to lift a whole section from another website and claim it to be an actual representation of one's own business activity, when it emphatically is not, is completely unacceptable when soliciting investment.
The irony of Gain stealing Hashocean's fraudulent lies and claiming them as their own is not lost on me.
Due to high influx in refund request because of speeding price hike of bitcoin we are unable to process your request right now unless price comes to a stable value.
A refund guarantee is a refund guarantee, full stop.
If their mining is as profitable as they say, the only reason not to refund is because they have no money to do so. Where is it?
Lets say you invest 1BTC to buy hashing power.
The person who sponsors you gets an immediate incentive of 5% of the amount invested i.e. .05 BTC
The network of people above you also gets incentives on the investments made by you to the tune of 10% on matching of investments in their left and right networks, translating to around 40% of the invested amount being distributed as incentives.
So in this case, .4BTC is distributed as binary incentive to the network above you.
This is why MLM is so toxic for those who in invest in the core business, as opposed to those who treat that as simply "key" money to unlock entry to the commission aspect and make more money selling the concept than the concept itself makes.
