It actually seems common for less developed countries to have better internet than the more developed ones. Germans always complain about their internet, for example. I believe the reason is simply that your country laid down lines relatively recently, so they’re compatible with high speed internet, while Germany laid down their lines 30 years ago, so they’re fairly shitty in comparison. It tends to be a lot harder to convince governments or bosses to replace something that seems to work fine, and it can be costlier too.
It has absolutely nothing to do with the lines, but the headends. Coax is very capable of transmitting lots of Data fast. Due to the tree topology of cable however, the headends have to be extremely fast. If everyone on the tree of 100 has 1000 Mbit, that headend needs to have 100 Gbit of capacity. Most of those headends however cap out at 10 Gbit and sometimes service up to 300-500 ports. German cable providers cheaped out and didn’t upgrade their infrastructure for quite a while. The coax line technology didn’t change in the last 30 years.
