From Time Teller (I don't think passive income for this platform would be sustainable as it is in waves platform.
Very few assets attain their success in that platform.
Actually, I can't even name one that I know of that achieved real success.
The challenge also is how to have active trading in waves dex. They are not that popular as compared to eth platform.
Though, there are a lot of eth tokens that are crap but a lot of them also emerge as successful.

REPLY FROM QUANTUM
HELLO TIME TELLER,
I just read your post... And I smiled, because you did not read our Contract Paper and by the way you said you don't think..
So If you did read CPaper, it was stated that Portfolio Income
is only an alternative program by QNG... Which will run for 8 months
(Nov - DEC PRS is paid in every 7days, and from Jan to May/June PRS will be paid in every 14days). This is our make up for earnings
until We setup MASTER-NODE in JUNE 2019..

NOTE: We did not do an ICo and We have Airdrop over 6.5 Million Already for free... And Volume is Building on Waves DEX
Also, Quantum Node is just 1month 9days old today... Join our Telegram to ask more Questions if you have... (t.me/qnode)

Believe it or not... We are on Two Exchanges already as made know above..

So if you are still thinking of Sustainability you will be left behind, Because We have paid all NOVEMBER PRS and completed..
QNG owes no man..

Thanks for the analysis you gave.. but Just stand aside and Watch Qnode break the records..
OUR Site will be released Before 8 December... [/color][/b]
