This is one of many reasons why I don't like loan with interest rate. I prefer like to use crowdfunding like we usually do in ICO. I think crowdfunding is better then only lend money. Crowdfunding that companies did in ICO not only lift some weight from the company but also gives big profit if the project is succes. Just imagine if those countries do crowfunding using cryptocurrency and every that cryptocurrency holders will get benefit from the project that the governments make. Anyone can get easy money fron loans but the impact is very bad.
I'm trying to understand how this will profit the investors, the money raised will be used for projects in the country so what does the investors get? Same without tokens majority of the project that did crowdfunding are producing today. Majority of the countries taking this loans aren't using it for productive things which is why they're getting indebted. Imagine a country borrowing money to pay her workers and still this workers don't get paid fully due to corruption.
If this loans were taken and invested into structures that'll be bringing in revenue to the country economy and sure the loans could easily be paid off but no the corruption in this developing country is what is weighing them down. There's no gain in borrowing to eat instead you get indebted more and that's what's happening.
