cdrx, By saying "money factory", I mean that currently if the JSE had real value as it is assigned in a symbolic way, compared to mining MONERO you would have to invest up to 4 times more money in a computer capable of mining the same amount of coins equivalent to those of JSE, and if we talk about ETH you would have to invest more than 6 times the amount of money you would invest in a computer equipment that mine a similar equivalent in JSE.

The programmed difficulty of BTC has become the worst enemy of this currency, because it seems that there is no way to backtrack to this configuration and that causes a problem, see as an example to eobot.com, where the contracts to 5 years, according to your ROI calculation system would recover the investment in more than 75.68 months, which means 6 years with 3 months, so you would lose if you invested in eobot.com, and the only way to have profit would be to use your system of "mining of GHS", although obviously it is not a guarantee that you end up having a profit, but you can still be overpaid by the level of difficulty of mining and you will simply lose money instead of winning.
