Hi guys!
I just migrated Safex coins from old wallet to the new wallet. I am thinking about selling my SFX and SFT. What is now the best option to sell those? And probably most safe?
I am still not sure to do that but would like to know the options. 
You should probably go to the SAFEX website. There you will find the instructions that you need to follow in order to sell or trade your SAFEX.
