Why do I Trade Altcoins against Bitcoin?
Bitcoin is here to stay:
I believe in the long-term prospect of BTC - I can simply invest in BTC and watch it grow.
Bitcoin is the Gold Standard:
I see Bitcoin as the "house" that altcoins are built on. It has the biggest network of nodes, though Ethereum does compete. However, Bitcoin has been around the longest.
I want more Bitcoins!
I want to invest my initial capital in Bitcoin. Then convert into altcoins when they rally against the bitcoin. When I convert back, I will have more bitcoins. Meanwhile, it might be up against the USD too. Double the joy!
