Poloniex is the most prestigious U.S. crypto exchange, accepting transactions from all countries in the world, after the 2014 attack have invested a lot in security and managed to improve their reputation again, allows to operate with leverage and has a huge variety of cryptocurrecies available.

I like Poloniex because it has more than 75 cryptocurrencies available, also 4 base cryptocurrecies are used to exchange which makes the exchange experience more comfortable and inexpensive while other platforms only offer 2.

I like that you can trade with leverage, has a huge list of cryptocurrencies that you can access in Poloniex and has a stop-limit to reduce risks, allows me to diversify the cryptomonedas portfolio of my clients and get better results.
