Click to earn, at least when "referrals" are involved, sounds like it is basically similar to such over-simplistic "make money from home" as the various versions of an "
Infinity Traffic Boost Plan".
I say over-simplistic because if you simply send the viewers of your ads directly to some third party site you are "wasting traffic"; traffic should be recycled.
In other words before you send a "referral" to anything, such as to go sign up for a telegram based airdrop or anything else, you should get them onto your own "list", because online marketers like to say "the money is in the list".
We here I suppose, if we trust the enduring nature of this forum and all the various free open source projects trying to make forever-storage so that our data we make today can reasonably be expected to be available in any holodeck anywhere when "the Federation" heads toward the stars once the Star Trek mythos is brought to life here on
the planet known as Earth, could maybe argue that this forum
is one of our "lists" so once we get folk to come here we recycle them using posts here rather than needing a "mailing list" or "membership site" of our own into which to "capture" them.
There is an entire industry "out there" though based on click to (if you do it well enough) earn that does base itself in mailing lists and membership sites; I of course have also my own examples for you of those too, my
No Upfront Cash "empire" of mailing-lists and my
LFM Knotwork membership-site.
Yet here I am, hmmm...
In my own experiments so far, crypto has for me been far far more lucrative than that whole clicks thing, even given I have an "empire" of mailing-lists
and membership sites. Heck I took offline umpteen membership sites long long ago, my whole family of Magickal Mystery Tour, Teach the World to Fish, Space Cadet Academy and more. See archive.org's "wayback machine" if interested in such ancient sites or the history of "Knotwork sites" ("Tying it all together...") in general. Still maybe a couple other membership sites left somewhere as I tried most free open source membership-site software available at the time(s).
If the telegram airdrops scene is going the way of the whole pre-existing click for credits, click for views of your ads, click to potentially earn from home in your pajamas etc scene then maybe that niche of crypto might be heading toward "not as lucrative as crypto" if the focus is on the how you earn it part rather than on the wow I got some actual crypto, NOW I finally have my seed crypto to get started into the lucrative part...
