Yieldnodes, in my experience, perform exactly what they state, and their user experience and communication are fantastic.
You can take out money in either Bitcoin (BTC) or Sapphire (SAPP). In the future, Tether will be an option, but there may be a fee because of all the conversions. For BTC/SAPP, there are no withdrawal fees.

Personally, I believe the founders to be quite open and sincere. They use independent specialists to "monitor" their business operations and confirm monies are being invested in servers, masternodes, etc., as indicated. In addition, they make regular video appearances, offer members monthly updates, and keep us updated.
In the 5 full months that I have been in this opportunity, the average yield has been slightly above 11% per month.
Sapphire (SAPP) has been introduced as a withdrawal option - exchange SAPP for vouchers and goods (e.g. Amazon, Netflix, etc.) at sapphireshopping.com and, if selected, will release on the fourth of each month (Bitcoin is 8th).
And they have an emergency contact system – pop in your next of kin details and a number of months. If you don’t login to Yieldnodes within that time frame, your next of kin will receive an email.
