Why do you bother to ask this question anyway? Internet is not that too much to pay if you have one in your house. Even a simple working students can pay up the cost of the internet. It's unlikely that a broke could not pay their bills though but if your salary is above the average then you can make a living already. Not unless if your salary is below the minimum then you are broke af and you can't even continue to do your crypto job with that.
In some countries cost of mobile internet is still to high,so they prefer wired connection modem which is more cost effective but in most of the countries internet is getting more cheaper and more places offer free wifi at high speed.
