from the numbers you provided wouldn't the return of investment be 3% per 24hrs not .3%? 1.00 investment, 24hr 0.03 return = 3%. If the three percent is the case then you could conceivably get a 100% return on investment within around 34 days.
Is this correct or am I missing something?
You are absolutely correct, my Maths is out by a factor of ten. I'll blame 'trying to do too many things at once' but colour me embarrased none the less.
For an investment of 1 BTC, you would receive
0.705 Nubits in 24 hours not 7.05 as previously stated.
Apologies for my misleading statement before, it really wasn't intentional.
