This is the problem with coins that do not have the backing of the Bitcoin miner network (or similarly staking network). There is a reason that Bitcoins are worth what they are today. On these smaller coins with only a few hundred thousand dollars of 'hashpower' going for them are insanely easy to attack - as demonstrated. That is why these coins are not worth that of a Bitcoin.
The security of the millions of dollars of 'wasted energy' is why there are no Bitcoin double spends in the news.
That's a problem only related to Poof of Work which is not a good protocol for any coins, specially new ones.
Well yes and no. There is probably only room for one POW coin in the world. POW has very strong assertions about the requirements to attack the chain. POS or any other system employs tradeoffs.
That said POW is not novel and no new coin should center their consensus protocol around it.
