They are very new and still in Bêta phase, there are some quirks (and that is why I did not made yet an Official Announcement via Riecoin Channels), but I can definitively vouch for their Staff. I think that they have a lot of potential and that it was worth getting Riecoin listed there.

Notably, finally an Exchange that does not frown upon Miner Deposits, they even encourage Miners, and do not have a formal Minimum Deposit apparently (of course be reasonable and do not send Dust), much better than NonKyc for smaller Traders and Miners.

I invite everyone to try NestEx for Riecoin Trading and set up some Liquidity Pools!

Of course, as for all CEXs, only deposit amounts that you can afford to lose.
Though it seems that they have plans to actually Insure Deposits, that would sure bring some peace of mind!
