When will we have micropayments?

One of the things this author finds most baffling about the online world we've developed is the lack of a clean, easy, near-universal, private system of micropayments. The suprising and dismaying absence is nicely described in this article, asking

Where are my digital micropayments? Where are those frictionless, integrated ways of exchanging money online—cryptographically protected to allow commerce but not surveillance?

and lamenting:

Of course, we already make payments online all the time, but under current conditions, frankly, it sucks to do so. If you buy things directly from small vendors, you’re stuck entering your credit card information, your email, and your billing address on site after site—sinking ever deeper into the surveillance economy as each digital form puts your personal details into someone else’s database, while also giving hackers ever more opportunities to filch your data.

I've never seen a convincing argument as to why this is impossible, just "micropayments fail over and over." But that can't go on forever — the prize is just too big. (Note also that my understanding is that China has put together a system that works, though I don't know if it is as private etc. as one might like.) So I ask:

When will the US and Europe have a workable system of micropayments?

The question will resolve when, with less than 10 minutes of effort, I can set up a "wallet" that will allow me to spend less than 25 cents (2019 dollars) by clicking less than two times, on at least 10 of the top 50 internet sites as listed by a reputable source comparable to 2019's Alexa, and where each payment does not show up as an individual transaction on a credit card or bank statement.


Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
