Ah damn, while I have no advice for you, I'll share my experience as well.

I wanted to buy some Electroneum and the only place to do it was cryptopia. So, I would have to send some bitcoin to cryptopia wallet.

But bitcoin transaction fees were to expensive and I wanted to avoid that. Ethereum fees have also increased. So, my choice was litecoin. So, I sent some litecoin to my cryptopia wallet, which I would exchange for electroneum.

Lo and behold, processing was not a smooth thing. Then when I wanted to exchange, LTC wallet had been frozen indefinitely. What was I left to do?

Luckily I was able to withdraw the litecoin from cryptopia to another (wallet) - of course with some fees. And I thought I would pick another coin and send it to my cryptopia wallet to exchange it for ETN.

But on a second consideration, I left it go. And all the fees added up to $7. All for nothing but some hours lost...

If ETN wants to up their game, they need to be in many more exchanges and not depend of cryptopia, which seems to fail many of its users. And we know other exchangers have done that in the past for STEEM and SBD (think poloniex).

Anyway, I hope this helps someone and I hope you're able to sort things out as well.
