Can anybody give an advice for a trustworthy altcoin exchange to transfer remaining funds to?
There is no such thing as a "trustworthy altcoin exchange".
This wasn't exactly the question, there' surely sort of a ranking, I think.
Keep your coins in the wallets or cold storage.
Of course I already do so. My „crypto-fortune“ isn't really big, and for the main part I hold the keys, not some exchange.
I had some old buy orders being executed due to panic sells on MCX when the announcement came… Anything I cannot sell for a reasonable price must obviously be transferred elsewhere soon. I've got some START, MNC, PPC, and few DOGE now, and I haven't yet set up wallets/cold storage for any of those, and now I wonder where I could sell these funds for BTC.
Since I've read something negative about Cryptsy somewhere, and I haven't found an exchange for all of the above currencies, I simply asked here.
I'm holding only around 0.23…0.28 BTC in total on MCX, but I don't like to give that all to RS. Internal MCX transfers do work and cost nothing, so I offer hereby to transfer my "interest and fee dividend dust" on LTC, XPM, DVC, CL accounts to someone owning enough to withdraw. If you want, you can give back some START, DOGE, PPC, BTC, MNC.
As you can see, I was just playing around a bit, not trying to make a huge fortune by trading cryptocoins.
