Don't really know if there are lot who will agree with me but when I first enter the cryptocurrency market, I used KuCoin exchange for my daily basis of trading for bitcoin which in my opinion is the best decision I have made. These are the things that I considered when choosing my exchange:

• Authenticity and security
• Supported tokens
• Fee structure
• User friendliness and simple user interface
• 24/7 good support since unreasonable things can happen anytime
• Good liquidity/volume for better market price

So far and still up to this date, I am still using their exchange as they also have loads of events/campaigns which gives me extra profit and also holding $KCS is a good thing for fees and bonus on their exchange, their bonus % wont even can get on banks lol. Try getting Bitcoin or maybe an alt like XRP It will be a good start on you! Join on their campaigns too
