You are essentially entrusting Yieldnodes with your funds and expecting a profit split in return. I've been with them for almost a year and am quite content.
May 2022 quick update: this has been my best, most reliable, and consistent high-yield investment so far (with the best communications, too!).
April 2021 (profit on yieldnodes: 12.7%)
Once your deposit is received, it takes 7 days to get your funds ‘masternoded’ and start earning. This can feel like an eternity when you’re excited, however the good news is that any deposits via compounding your returns are immediate (I’m now just partially compounding & partially withdrawing).
Based on their 18-month average return of 11% per month, a $5,000 'node rental' should have grown to be worth $8,425 in 4 months, and you would be earning roughly $835 per month in month 5, providing the 11% average persisted.
Yieldnodes keep a maximum of 15% of the income generated by their service, with the remaining 85% going to participants. Profits are generated primarily by masternoding activities and their ever-expanding ecosystem, which includes exchange activities and initiatives that they administer and foster, such as SAPP (Sapphire) and third-party coins.
Request a withdrawal by the 15th of the month, and you'll get it by the 8th of the next month. Note that deposits are locked for 6 months, however yields can be withdrawn monthly as per above.
