For the past several hours I evaluated whether BTCC could be a viable alternative to mainstream derivative exchanges. The more I looked into it, the more red flags I collected:

• BTCC confiscates the entirety of your deposit if it amounts to less that $120:
  (the minimum deposit amount for BTC is 0.0021 =~ $120)
  
  
• the withdrawal fee for BTC is also $120, documented in fee schedule
• for all currencies, an additional 6% withdrawal fee is levied if your account has ever used the "buy crypto" function of the exchange (documented here)
• the trading API reference documentation is hastily written like a careless high school assignment by someone with no comprehension of either English or JSON:
