Thank you.
Even though the link is broken I will show you my opinion
If we want to trade and try our skills if we are good in trading then the first thing that is most common is to have bitcoin(s), and send them to the exchange and mostly all crypto exchanges are available in bitcoin to exchange in other coins.
Maybe I didn't choose bitcoin but there was nothing else that could replace bitcoin and have the power of bitcoin that has and still have nowadays, even though there are some ups and downs about the bitcoin but still is good, especially with SegWit I see many benefits by having less transaction fees.
