Also in Europe, I've been using Discord almost daily for 5 years now, and always impressed by the voice quality.

I'm not sure how you've been using it for 5 years, when it's only been out for 4 (May 13th 2015)[0].

I'm just one example, but I've been using it since launch day. So 5 years is getting close.

Rounding 4.7 years to 5 seems like a perfectly acceptable estimate for a comment.
