there have been sent approx. 5000 btc to the Exodus address, each equals 100 MSC + average %20 bonus which should equal to 600K MSC.
To this you can add the future 10% that will be added gradually which will be finally about 660K MSC (which shall be less since 60% of bitcoins arrived in the last week that only had 10% bonus reward)
May you explain us how did you arrive to 50M MSC number???
Also where did you buy your logic from!?
