Bitcoin Confidential was just listed on StackOfStake. I've never heard of SOS before but the more I got into it the more I like what I'm seeing. Basically sign up, ship your coins to the site and stake them free of charge, sit back and earn passive income. Reminds me of Blockfi for btc. I hold some $BC on a desktop wallet from a Smartcash airdrop. Looks like I'll be staking my coins on StackofStake.
This is from their website below:
StackOfStake was founded in March 2018 as an instant shared masternode service for SCRIV community. After the launch and several months of successful operation, the team decided to expand the variety of offered cryptocurrency projects presented at the service.
