Kraken is my favourite...


It has a reasonable selection of coins to trade with the most common fiat pairs.  It has been established for a very long time ( from the first group of crypto exchanges).  It is based in the uk, Germany.   As with most exchanges (bar coinbase and a few others maybe), it is not regulated by a national body as far as I am aware (neither is Binance, bittrex).


you can place advanced orders like stop buy and stop sell as well as take profit orders!! the first two are very good if a strong break above or below a certain price is likely or predicted.


you can trade most coins with usd, euro, gbp etc.  The liquidity is fairly good.


Most importantly is allows margin trading on about 5/6 coins.   Btc/Eth with 5* leverage, the others etc, xmr, rep 2* leverage


With a verified level 4 account you margin trade upto $50,000 of borrowed funds, For level 2 $500 (excellent for newbies to learn) level 3 upto $5000 of borrowed funds.
