Even if it was true, do you think this could be an excuse for people buying/selling bitcoins with tens of thousands?
I think it's an excuse for everyone, both small and big Bitcoin users. Bitcoin is still rather new and from my own perspective, finding banking partners that are stable and willing to work with Bitcoin related companies is maybe less than 1% of the existing banks. So we should generally be thankfully for them trying to break into a new market.
Somehow there are like 3 other services using EXACTLY same payment processor/bank and they're not having any kind of issues.
Bitcoin is not new, we could call it new 3 years ago. There are many services which does exactly what advcash does and they're fine.
And ofc it's unprofessional service, how could anyone managing a business get into situation like this? To have the most important part of their business suspended for 20 days?
10 days ago i would be far from saying that they're "scammers", but look at this situation:
Service is dead for almost a month, they still have deposits enabled. Means they make money for service which is not working.
How is it called, if not a scam?They should have shut down registration, deposits and so on.
Now AdvCash is not working for 20 days straight since 13.04.2016
