I say, probably Binance, looking from what I read about them, especially Quora posts by Marius Kramer, the only one I really listen about cryptocurrency.
But I have bad experience with Binance, and oppositely, I have good experience with Kucoin, for similar problem.
So… the story was, someone tried to hack my Binance account few months ago, but failed.
I get notified about that on my phone.
Thankfully my account was safe.
I reported the incident to Binance, as I thought it was a good deed to do. Just as Binance told me to do via their e-mail to me after the incident. To report any suspicious activity with my account to them.
So, I reported it.
Few hours later, after I reported,…Binance froze my account!
Hey!… It was not my fault!
I was upset, but tried the procedure to unfreeze my account.
I cannot enter my Binance account without doing ‘some’ steps first.
‘The steps’ are tedious.
It keeps telling me I’m failed.
Tried it more than three times. All failed with ridiculous reasons sometimes.
No way to personally ‘humanly’ contact someone in Binance, except through their ‘automation’ mailing/report system. Sucks.
My Binance Account with my funds is still freeze until now.
Few weeks before that incident with Binance, I experienced almost same thing with Kucoin.
Not like Binance, aside from ‘automation’ system, they give us way to communicate with ‘real human’. Only needed 1 day, my account and assets get back to me safely.
I was keep trying, until for about few weeks after that, but always failed, and I’m getting bored trying to recover my Binance account.
And it was even not my fault at the start
So I stop trying, it’s been more than few months now, I do nothing about it.
I will try again, perhaps, but perhaps later.
My asset in Binance is not big, but still, I hope I can regain my assets and account.
I’m disappointed with Binance.
Update:
After almost 1 year, eventually I can make Binance to unfreeze my account & my funds in there keep intact. What a tiring experience. Still, I have to say, Kucoin’s 24 hour direct chat facility with real human officer is superior.
