Recently I started browsing the altcoin section, and its seems that there is an increasing amount of altcoin or tokens that serve different purposes. So i've been thinking, if the majority of these coins become successful, and people use different coins to buy different product and services, doesn't this make everything more complicated? Since whenever you buy something you need to first switch to a specific coin or token, and this incurs transaction cost and slows down the process, defeating the purpose of using cryptocurrency.
