For a commodity like bitcoin and especially with bitcoin mining where mining difficulty and total number of miners change all the time, speculating on the ROI for bitcoin mining can be difficult or futile. ROI is determined by a few factors – the number of bitcoins mined in a given time, and the price of bitcoin at any given moment – both of which changes daily. There is also the changes in mining difficulty over time, and switching of repurchase percentages by individual members and the full and partial shares that they own. Based on historical records, the break-even period is usually about a year to a year-and-a half, although some members have been known to break even as early as 6 months. It all depends on the price of bitcoin and when it is sold. Just to give an idea, before the last halving in July 2016, a Founder Pool with BitClub Network typically earns about 3 bitcoins per year on average. Even as the amount of bitcoin supply halves every 4 years or so, its value generally appreciates a few folds in the same period, resulting in a net gain in investment. With BitClub Network, members are also given the full control of how they would like to allocate their daily earnings to repurchases of partial shares. A higher percentage may be set on the repurchasing of partial shares, which provides the member with a higher number of partial shares in the pool, leading to higher earnings once the percentage is set back to the default minimum at a later period. Pool mining with a community like BitClub Network generates higher earnings in bitcoins compared to mining from home, especially after deducting earnings for 24/7 overheads, maintenance and keeping up with upgrades.
