Proof of stake coins have been undervalued and overlooked for far too long. Back in the day, owning a few coins from projects like Navcoin, GRC, Pink, PIVX, etc., and keeping the wallet open was enough to earn passive income. It was that simple.
But now, the landscape of staking coins has shifted dramatically and become more centralized, which is unfortunate. But that doesn't mean there aren't any great options out there. In fact, I believe there are still some fantastic staking coins available in the market. As more and more people start to look for ways to earn passive income from their crypto holdings, the entire sector is going to experience massive growth.
Cosmos, Polkadot, and Tezos - which you mentioned - are great examples of the top staking coins right now. I did my own research and I can say that these coins are not only solid investments, but they also have some of the most active and engaged communities.
I think the crypto sector is way past the PoS hype, especially when there are too many PoS coins on the market. You can see why ETH's transition from PoW to PoS had little-to-no effect over the cryptocurrency's market price. Now that a US government agency decided to prosecute a crypto exchange by providing staking services to US-based customers, investors will steer clear from anything PoS-related as much as possible. One thing for sure is that PoS is not what it used to be in the early days. Back then, you could stake Peercoin, Blackcoin, and some other good-old coins in a decentralized manner by just running your own node at home. Nowadays, staking is done by delegating your funds to a third party (centralization). The aforementioned coins still exist, but they're highly-unpopular compared to new PoS coins such as ETH, ADA, BNB, and DOT. I guess investors prefer centralization more than anything else.
As far as the next crypto craze is concerned, I'd say it's a wild guess. We can't tell for sure what will become popular in the crypto industry, especially when there's a lot of negativism surrounding it. The bear market is going to last for long, so I'd focus on accumulating as much coins as I can to build my way towards the top. Ultimately, what matters is decentralization. As long as decentralization wins, there should be nothing to worry about. Just my opinion
