If you really wanna bet on ethereum, consider instead legit projects without ethereum's rubbish, such as ARK (today +10% and set to grow until end of week)
or ETC
dPoS is bad, without PoW it is impossible, decentralization is lost in ARK, XRP, XLM, EOS, NEO, TRX and same other
and ETC is vulnerable to attack 51 of Nicehash
crypto51.appWhat's so special to PoW? Even Ethereum wants to fork away from it. PoW is asking for a lot (initial hardware cost, energy cost, environmental cost, risky ROI which depends on future products) and offers little in return (safer network if it's a top 10 coin). As you said, a coin with PoW which is not very high in price will be left vulnerable to attacks, like ETC.
So far ARK is doing fine with its decentralization, I don't know what are you talking about.
As for XRP, it's not dPoS, there are many validators and they're growing! Among the validators are Ripple (ofcourse), University of Nicosia, Berkeley University of California, some exchanges or at least one I can see in the list and many more... full list here:

EOS froze the coins of one of the bloggers with suspicion of questionable origin. So what can be done on any coin with no PoW
and if they impose sanctions and freeze all the money of the russians? I am a resident of Moscow and would not want to lose money. I do not want to switch to the Waves or Chinese NEO
