If anyone decides to do some arbitrage it is actually good for the lykke exchange as it makes more colored solarcoins helping liquidity.
For example
I sent 18,000 Solarcoins to lykke exchange. They got converted to colored Solarcoins.
I then traded them for bitcoin and sent the bitcoins to Bittrex where i then re bought my original 18,000 Solarcoins back plus made about 500 free Solarcoins.
