I have been on these forums since 2012 and I can also vouch for ADK. I purchased a good amount of ADK a few months back and cashed out a nice chunk and I certainly did receive my BTC.
Yes the exchange is buggy and is currently down and yes there have been withdrawal delays but I can tell you this - you will get your BTC in the end!
It is obvious that the FUD comes from posters who you can't tell what is lower - their age or their IQs.
Trying to read the garbage posted by goingmobile or 12inchdickinhisass is literally like listening to someone take a dump beside you. Just do yourself a fav and put them on ignore!
