Now here are the conundrum, do we celebrate the centralization of money exchange from Fiat to Crypto (Bitcoin) or visa versa... OR do we regret the move to the centralization of Crypto currencies.
Yes, it was inevitable that it would have gone that way... but centralization come with a lot of negative connotations, namely :
1. Creating honey pots for Hackers
2. Institutional corruption and centralized failures. (MtGox)
3. Market Manipulation (Fake trading volumes ... )
4. Higher fees (Exchanges add additional fees for the trades)
5. Introduction of an intermediary and the reliance on them.
6. Destruction of Pseudo anonymity (KYC)
7. No control over your own coins (Private keys)
8. Censorship of use... (They do not allow certain transactions)
These are just some of the negative things that were introduced with the Exchanges coming into the Bitcoin scene. (Not your keys.. not your coins)
