Do not use Crypture (Imposter) for anything serious. I used them for just over a year for small trades and it was okay. When I deposited a larger amount and traded more, my account was flagged, my withdrawals were delayed, and I was asked to explain my trading. They treat active traders like criminals.
Pros: Low minimum deposit|Competitive fees|Automated trading options
Cons: No phone support on weekends|Alert system is basic
