3 days ago I sent 493 SBD to the poloniex account. It's still not showing up and I understand that they kindof have issues with their operations near hardforks. That's not okay.
I opened a ticket about 3 hours after I sent them the SBD. I haven't received a reply, yet. I understand many steemians complain and post about this.
I look into the steemit wallet of poloniex and I saw that since my transaction, there are at least 450 operations on their account. These may be currency sent, received, otherwise.
Now, I may not know about how things work with these companies, but 450 operations can be run by a bot in milliseconds.
If they are run/verified/processed by 1 human operator it could take a few hours at most. Multiple operators could get it done in less than 30 minutes. Does this sound unreasonable?
I don't know where this is going to lead, but I remain hopeful that I and the rest of you steemians in similar situations will get to resolution as soon as possible.
I suspect many of you are frustrated and looking for alternatives for future operations. That is reasonable and understandable.
I want to end this unusual (for me) post in a positive note. Steemit, in my view, is doing very good at the moment. And I am excited for what follows.
Until then, I remain a mixed bags of 'feelings' :)
