By 2021, another buzz word will be discovered and launched onto.
That's certainly true, mate. Most decentralized exchanges use the term "decentralized" to give investors and traders a sense that their funds are secure against malicious third parties. But as long as these exchanges rely on centralized infrastructure, they'll be subject to single points of failure just like any ordinary centralized exchange. Requiring users to comply with KYC/AML laws, makes matters even worse. The only true decentralized exchange is Block DX as everything is built on the protocol level. There are no centralized servers hosting the exchange, nor a central operator requiring ID verification. This, alongside atomic swaps, could save "Decentralization" as we speak. We need more people to support truly decentralized projects in order to make crypto/Blockchain tech as resilient as possible.
Of course, money talks more than anything else. Centralized exchanges have the most liquidity on the market, which explains why people have been quite fond of them. Not to mention, centralized exchanges are much easier to use than their decentralized counterparts. As far as cryptocurrencies go, only Bitcoin is the most decentralized Blockchain network in the world. Others are simply "words" without delivering concrete results. Ethereum is the only altcoin that's closest to Bitcoin in terms of decentralization and active development. The rest are simply semi-centralized or utterly centralized. TRON, EOS, XTZ, and basically any other cryptocurrency that relies on DPoS or RCP (Ripple Consensus Protocol) are centralized. They're just using advantage of the word "decentralized" in order to attract as much investors as possible. At the end of the day, people will decide which projects to support and which to leave behind in the dust. Just my thoughts
