Just used the DOGS app and got around 4800, didn't invite anyone or did anything else.
Looking at bitget's pre-market, my stash is worth around $5. 
Might not even bother...
This is to say that you must have been on telegram for over 5 to 6 years then, the app told me I've been on telegram for 4 years and was given around 3020 tokens, the referral system isn't that profitable afterall, as I managed to invite 9 persons but earned around 300 tokens in total.
Last last, I managed to accumulate around 60k dogs tokens, what helped me was the daily check-in reward which I only missed few day, the system rewards users with 1400 each day you check-in on that app, plus 20,000 tokens for inviting more than 5 persons generally.
So far so good, this possibly can become the biggest airdrop in history, but not gonna happen immediately since there are 550 billion tokens, which over 400 billion entering the market on 20th, theres going to be a lot of sell pressure, I personally plan to buy more dogs tokens and hold for the long term.
