Added recently as a tipping option on Publish0x, Loopring (LRC) has gained a lot of attention. A lot of articles about it, a lot of searches I presume, it's practically the newest toy of the platform. I admit that I haven't heard of the LRC until now, but thanks to Publish0x I had the opportunity to learn something new.
Although it looks like a good asset to hold, some users will probably want to trade it. The good news is that it's a pretty big list of exchanges where you can do it.
As trading pairs you can choose between BTC, ETH, USDT, EURO, KRW, INR or UQC. If you are not conditioned by an exotic trading pair, you can choose between well-established exchanges like Binance, OKEx, HitBTC, Bitfinance and others or some small ones like Bitbns, Alterdice or Livecoin.
I don't know all of them, so all suggestions are most welcome. For new users without trading experience, my personal recommendation is Livecoin. I have been using it for over a year, it's a small but reliable exchange. It's very easy to set up an account, KYC is not mandatory and they have a quite simple interface for trading. The trading fee is 0.18%. For FIAT withdrawals you can use Payeer or Perfect Money (fee @ 2%), but minimum withdrawal is 10 USD. If you just want to change LRC to another cryptocurrency, you can withdraw a lot of cryptocurrencies with very low fees. A few examples: 0.02 DASH, 2 DOGE or 0.01 WAVES.
