Today BitMax finally began allowing staking Harmony ONE, alongside their already existing staking products - KAVA, XTZ, and ATOM, all available to be staked at reasonable rates of returns comparable to other exchanges.
However, today BitMax introduced staking of ONE at a huge 68.94% per annum, something which obviously is hugely ahead of other exchanges such as Binance's 8-10% per annum.
I don't know how BitMax is able to offer this percentage, but supposedly those who stake over 2000 ONE will receive this rate of interest. BitMax is obviously a legitimate exchange which has existed for a while, so it will be interesting to see how this develops.
