Instead of this, going with more guaranteed coins is better. I mean I could wait for ethereum pos. It would be the best thing for me, because I don't trust other unknown coins and projects.
While there are many good PoS coins in the market to choose from, in my opinion, Ethereum will become the best PoS coin in existence. One of the biggest differences that Ethereum will have against other PoS coins would be the complexity of its consensus mechanism. It will become the most advanced PoS coin in crypto land with smart contract capabilities, further boosting its adoption in the mainstream world. Once Casper goes live, you could expect a huge increase in transaction throughput and reduction in energy consumption.
If Ethereum is now between the $1,000 - $1,200 ranges, it could easily increase it value when it migrates to PoS. That's why, it may be best to invest into Ethereum now while it is still PoW, as it may become much more valuable once it does the shift towards the new consensus mechanism. Therefore, when making your list, consider Ethereum as the priority for your investments.
Things aside, there are other good projects which are known within the blockchain industry that have incorporated (or will integrate it later) PoS mechanism. Such coins are Cardano (ADA), Stratis, Ardor, and more. If you make a research about them, you'll realize the true potential these coins have over the long term. Just my thoughts
