Thank you OP for the detailed clarification.
CoinEgg did the same with IFC and XLM. I ended up liquidating my coins to BTC in loss to salvage what remained after the dump and moved all out to Binance.
PS In light of your thorough post, Im cancelling my HITBTC account thats been pending verification for a while now.
The more people that do that, the better for everyone in crypto!
I am sure you can do your own research about exchanges and try to find the best option! But DO the research ... dont make the same mistake, as i did ...
