It is true that it's easier to attack PoS coin, but it's sorta impossible for new coin to use PoW,otherwise, those with ASIC miner will dominate the coin.
There are different implementations of PoS, some are vulnerable, some are more secure than PoW.
It's not impossible for new coins to use PoW, especially if they run on an algo that ASICs haven't been invented for yet, or something like Myriadcoin with 5 independant algos. Myriadcoin is not susceptible to 51% attack, but you never hear much about it. Why? Because most posts here are from miners, who don't give a flying fuck about the future of a coin, all they care about is profits from mining. They can't fairly and accurately assess fundamentals and advantages of a coin and don't even try to. They cry scam to everything that doesn't let them mine and dump for a profit. And naturally PoS coins don't let them mine and dump, hence they cry foul as soon as they see the word 'PoS' in a sentence.
If the Algo is support by ASIC, the coin will be dominated by ASIC.
If it is supported by GPU, it would be dominated by big GPU farm
If it is a CPU coin, you are invite botnets.
If it is PoS, miners don't like it and big holder has advantage
Yes, PoW is dominant yet there are several examples where PoS has resulted in serious issues.
That's not a good argument to continue the PoS experiment.
PoW has its vulnerabilities too. And cryptocurrency as a whole has lots of serious problems too (eg inputs.io, mtgox). Are you going to say since there are so much issues in crypto currency, we should stop "experiment" or using cryptocurrencies all together?
