I do not usually post about cryptocurrencies or offer advice about what to invest in or where to do it. However i find Kucoin exchange very simple, straight forward and secure. It has a wide variety of altcoins to purchase/trade (150+). Also the trading fees are very reasonable. The trading fee is set at 0.1% of the asset you bought. You have a choice of NEO, BTC, ETH, USDT and KCS as trading pairs with the other altcoins.
Here is a screen shot of where you can select the asset you want to buy/sell.
Once you have selected your trading pair a screen like this will open where you can start trading with most of the same features you find on other exchanges.
Apart from that large number of altcoins (which increases almost daily) they have an awesome bonus feature for holding their coin (Kucoin share or KCS) almost like getting GAS for holding NEO. You get a percentage of the daily trading fees paid out daily to your account depending on the amount of KCS you hold. So every day you get bonus payouts of numerous altcoins albeit small percentages. Over a few weeks/months it all adds up and obviously as the prices for these alcoins increase so does your total wallet value. At the moment i have about 140 different altcoins in my account of which i only bought about 8 different coins.
They also have a referral bonus for referring other people to the exchange. You basically get a small percentage commission when the person you referred trades on Kucoin exchange.

A word of caution as always.... Do not take this as investment advise and always do your own due diligence. These bonuses will not make you rich over night, but it is always nice to receive free things that might one day be worth a lot of money.
Let me know what your experience with Kucoin exchange was like and how you find using it.
