From all the downtime and loss of customers do you think Agora at some point will decide keeping this up just isn't worth the trouble? If Agora's downtime issues aren't solved will there be a mass migration causing Agora to just exit scam? Or will they stay true and retire their market properly officially inducting themselves to the DarknetMarket hall of fame?
As soon as Agora is stable again, it will instantly recover any business that it may have lost. So no, don't think so. Agora is still king despite recent struggles.
