Lower commission for $ETH stakers and higher rewards for providers on
http://stkr.ioSimplifying the reward structure increases long term sustainability and competitiveness of the #Stkr platform
#Eth2 staking rewards go 85% to stakers and 15% to providers

Everything seems to be good about stkr but how reliable, secure and sustainable is this platform itself? And in case of breach, funds stolen or hacking will they refund us our original eth? Without clear answers to these questions i will not invest or stake with them because i have bad experience with similar platforms.
They should be sustainable as they are taking a cut from the staking profit. I hope the funds are secured and insured in case of any unfortunate circumstances. Not just stkr but many of the popular exchanges also have started pool staking of ETH. Some claiming to charge as low as 0.5% cut on the staking reward. So, there are many options users could choose from which they find reliable.
