Centralization creates volume, liquidity and so on. Not only on exchanges but in any market. That's why you have a middle-man in almost every business who makes centralization and then liquidity. At food markets, at crypto exchanges, at fiat currency exchanges, etc.
Platform evolves and we are witnessing more and more useful DApps. IMO DPapps are the 'true' future and I'm investing every free resources in it.
That's certainly true, mate. Considering that the world is somewhat dependent on a centralized model, many people have resorted to centralized exchanges. These same exchanges are largely dominant within the mainstream world. With unmatched liquidity and user-friendly platform, people are able to perform crypto trades without the need to worry about anything else. Of course, these centralized exchanges are prone to many risks such as hacks or theft. But most people don't seem to care about this. Even with the inception of decentralized exchanges, the centralized realm is still leading the crypto industry. This is bad since crypto was meant to overcome the middleman in the first place.
Given how big the crypto industry has grown, it's hard to be able to achieve 100% decentralization. There are too many players in the industry with a lot of power and wealth, making them hard to beat anytime soon (like Binance and Bitmain). At least, we could try our best in decentralizing the crypto realm as much as possible. The more distributed nodes there are for several cryptocurrencies on the market, the better for their decentralization. PoW-based cryptocurrencies like Bitcoin and Ethereum can be "solo mined" whenever it's possible in order to maintain their censorship-resistance. It's the best thing we could do at the moment in order to minimize risks of centralization as much as possible. But be aware that achieving 100% decentralization seems rather impossible at the moment.
Nonetheless, with the advent of dApps, DEXs, and even non-custodial mixing services, crypto could finally maintain its decentralized nature for years to come. There needs to be an effort from the developers, and community as a whole, in order to allow crypto to remain as is for the foreseeable future. Just my opinion
