Cryptocurrency exchanges are a vital aspect of this industry. Although they make it more convenient for consumers to embrace this new form of money, there are a lot of concerns associated with these centralized platforms. Vitalik Buterin is convinced that these companies are a problem and should burn in hell.
The world of cryptocurrency is about decentralization at its core. As such, one would expect the entire cryptocurrency ecosystem to be as decentralized as possible. Sadly, that is not the case as of right now, as this industry is mainly centralized due to mining pools and trading pools. The increase in decentralized exchange platforms may help change that situation in the future, but for now, no real changes are happening.
