Don't dwell in the past glory, you can't use all-time success to judge the stability and suitability of any business.
History always repeats itself, especially when it comes to crypto exchanges. Don't tell me you don't know this.Quote
The all-time high I even read was in 2017 and it's $130M but that is not the case here. Yahoo was doing better than Google some time ago, but can you compare the two in earnings now? Paxful was a better competitor and traffic trackers ranked it #16,947 while Localbitcoins ranked #42,159. That should mean something to you.
Aaah so Google is king forever, it will never drop from the top spot. Well, that means something to me 
I don't think so, if they lost due to KYC, why are the others with the same KYC flourishing in the business? What I have noticed is that businesses with their model accepting all manner of payment systems for P2P need due process to protect themselves and their customers because fraudsters are everywhere.
Did you ever have an account on localbitcoins before the mandatory KYC requirements came in? Trust me, their new KYC requirement were too strict and asking for too much personal information before one could get verified.Even Binance and likes of OKX have KYC verification but have not yet reached that level of KYC where you have to state how much you earn yearly, what kind of business you do and where your grandmother was born etc
You can look at the charts and interpret from the time KYC verification became mandatory on the platform - https://coin.dance/volume/localbitcoins
