What do you like best?
I really enjoy the care they took in designing the UI, specifically when setting up stop-limits and sell-limits, as well as margin trading. It allows for a very robust set of options when executing trades, evaluating charts, and ultimately getting your money back out. I have used a few competitors, namely Binance and Coinbase, and have found more success with Poloniex. The fact they are based in the US helps as well.
What do you dislike?
One issue I encountered was the response to my inquiry for account recovery. The automated ticket told me I'd hear a response in 72 hours, but it took closer to a week before I heard back. This was to recovery my 2FA and was not handled with the urgency I was hoping for.
Recommendations to others considering the product
Weigh the options of using every exchange before making a decision. Poloniex works for me as it offers a lot of tools I need on a daily basis, but some people may not need that level of complexity. Other exchanges offer similar tools but with more approachable UI, so understand what you need in order to be successful. I believe Poloniex offers some standout features and would recommend it to anyone looking to expand their business.
What business problems are you solving with the product? What benefits have you realized?
When you trade cryptocurrency as a form of income, it's important that you can feel confident in your tools. Poloniex has allowed me to set more automation, expanding my business and by leveraging the margin trading, you can earn even more.
