Cryptopia was my favorite exchanger with smooth deposit and withdraw, active chat and forum. After I saw all the complaints the last days/weeks I looked around in forum and chat and you are right. There seems to be no support anymore. Many complaints and support questions are unanswered. I hope, they will return soon to their old good service. Until this point I will only deposit little funds.
This is exactly my same approach. However, there are coins which are listed only there or so, so if you are in those coins you need to stay there, just trying to limit the parked funds there.
