Every blockchain today has those problems, the one more than the other. You think Steem is decentralized? Compared to proof of work the security is pretty questionable because it's a big circle jerk (a bit like communism). You think bitcoin is decentralized? It's not when it's mined and owned by a minority. (In theory a 51% attack is possible and encryption can be hacked with quantum computers.)
But why does it matter in the first place? Decentralization only makes sense when you need the security. Otherwise a centralized server makes more sense since it's so much more efficiënt. That's why most ico's are bullshit, they don't need a blockchain to begin with and if they do usually they don't offer much advantage to existing centralized apps.
@Drugwars is a very good example of that. They don't need a blockchain, in fact it makes the game even much worse. You can't launch a blockchain game that takes seconds to load every time you do something in-game. We live in 2019, it's no 2000's anymore. There are playstation and pc games with graphics so real it's almost like real life simulations. And meanwhile those scammers fuck around with blockchain tech to make an ancient game just because decentralization/blockchain is a buzzword that somehow triggers noobs their brains into thinking it's the next best thing. But in reality you are going at least 20 years back in time.
Not speaking of games and dapps on Ethereum where you have to pay a gas fee every time you make a transaction, so ridiculous.
It's not that it doesn't make sense, crypto and games could go hand in hand. But blockchains are to slow for such things right now.
Usually you can't have something that's fast, cheap and very secure. You can have high security but it's expensive to run and slow. There is a trade off between those things.
Not that it all matters. Fundamental analysis makes you smarter but understanding price action makes you richer.
