He is exaggerating or doesn't know math and dates. If the estimate time of 10 weeks from now which they can make all the spreadsheets available publicly and the payment of the participants which adds up maybe 4 more weeks (i.e. if they have a plan to pay their participants), it will not even get the year 2018 done. 2019-2020 is just ridiculous.
I indirectly meant to say that the spreadsheets will never be assessed and hence don't insult my intelligence (I may be even more educated than you

). It's better to assume that they don't have any intention to pay. Are you even a member of the bounty campaign?
I can't say that they are scam or not but the account of Frogman seems to be hacked. I'm losing hope to get paid anyways.
