Photo introduces an increased dollar rate for cheap goods

Our AliExpress, which is, came up with a new feature. Now, the cheaper the product, the higher the dollar rate for it. However, do not rush to panic. This only matters for cheap goods.

A digression.

As you probably know, there is a big international AliExpress - I'll call it And there is a separate structure, to which all work with Russia is given.

If you live in Russia, then you cannot buy goods through It's just physically impossible. Even if you just try to access the globalNew site, you will be diligently transferred to

When a Chinese seller with AliExpress sets prices for goods, he sets them in dollars. You pay them in rubles. The conversion from dollars to rubles takes place according to the internal exchange rate of, which usually changes once a day and which you can watch on our website. (Or better subscribe to our Telegram channel).

By the way, international has its own ruble/dollar exchange rate, and it is different. You can read about it here. But to ourIt has nothing to do with today's topic.

How to track the dollar exchange rate on It would seem that everything is simple. We find a product that costs exactly $1, look at its price in rubles. This looks like a product, for example. (These pseudo-products may disappear and disappear. If suddenly the link stops working - kick me in the comments, please).

Until yesterday, this one-dollar scheme worked great. And yesterday everything suddenly broke (thanks to Dmitriy / DVK62 from our chat, who brought this to my attention).

I start digging and discoverstrange. The cheaper the product, the higher the day it is the dollar. This is how the graph turns out:

(If suddenly someone is interested in digging, then the data set on which this graph is built is hidden under the cat).

Data for plotting

x_values ​​= [0.01, 0.05, 0.1, 0.2, 0.3, 0.52, 0.59, 0.61, 1, 1.06, 1.17, 1.25, 1.31, 1.42, 1.48, 1.64, 1.68, 1.98, 3, 5, 10]

y_values ​​= [ 155, 92.8, 85.1, 81.25, 79.9666666666667, 78.8846153846154, 78.7118644067797, 78.655737704918, 78.17, 78.122641509434, 78.0598290598291, 78.016, 77.9847328244275, 77.943661971831, 77.9256756756757, 77.8719512195122, 77.8571428571429, 77.7878787878788, 77.6533333333333, 77.552, 77.475]

I.e. for goods worth one cent exchange rate up tollara is generally unrealistic, 155. Well, from five to ten dollars everything is already stabilizing and today (February 28, 2023) tends to a constant - to 77.475. Which we will now consider the dollar rate for

There is no moral to this fable. Well, apart from the fact that now you have to be more careful when buying ultra-cheap goods.

If suddenly someone remembers numerical methods and can approximate this function, I will be grateful. Surely, after all, they consider it according to some beautiful formula. y=f(x). But what is this f?
