I dont think CZ will be dictator in crypto space. We have a lot choice when choosing exchangers and the influence of CZ only in binance ecosystem, and the coin listed in binance, listed in others exchangers too. CZ doing a great job in cryptomarket and i think its not easy for him and the team building biggest exchangers in just 2 years.
CZ always has a change and that is why many investors have great faith when participating in this exchange. In fact, the Binance exchange has done very well in controlling the market situation and they have many new strategies to encourage investors to participate in this exchange. I personally like to join the IEO because it helped me to earn good profits and this is the main reason why i am excited to trade in Binance
