in earlier announcements i remember that supernodes were categorized as Proxy Supernode, Miner Supernode & Full Supernode and required stakings 50.000 / 150.000 / 250.000 or so... In these examples in what purpose were proxy supernode or miner supernode created for? Because i see that announcement says only full supernodes (the one with highest staking) can receive commission from transaction fees and POS fees.

Now, with new 4-levels of supernodes, transaction fees and POS fees will be shared with all supernodes? or only full supernodes will get the commission?

I know, there's a sample showing possible earnings with estimated transaction amounts/day . But it's still unclear for me whether Masternodes / Tiers receive transaction fees - not RTA in POS, i mean transfers between wallets, will all MNs receive transaction fee commissions?
if the answer is yes, now who receives transaction fee, while masternodes inactive?
if the answer is no, does it mean we should wait for active POS points to become widespread to get reasonable earnings via masternodes (i guess it is, and not before 1 year at least, considering current roadmap) ?

Thanks,
