Well actually I have evidence.
There are only 6 or 7 PoS coins coins in the top 50 cryptos (and even less in the top 100), only HoboNickels gives 100% interest rate, the second highest being mintcoin.
As of peercoin, the PoS difficulty is 10, while PoW difficulty 154,904,621.505. Clearly, PoW save PPC from a 51%. And the moment people realize mutual fund schemes give many times better returns, they'll dump PPC for it. So actually, it's surprising why people are still holding PPC for it's negligible interest rate. I would like to learn.
Even HoboNickels, which has a return of 100% a year, has PoW difficulty of 10, and PoS difficulty of 0.003. Speaking of which it's peak has arrived, and never see it's peak again even if the dev is active (it wont die -- but it wont go as high).
Even mintcoin (100% PoS) has a difficulty of 0.243. It provides 0% protection and 20% interest rate.
Did you just time travel from pre-Copernican Europe to criticize altcoins? Because your critique has all the features of Medieval Occultism. Most notably, it is clear from what you have written that you have made judgements without even the slightest understanding of how PoW/PoS coins work.
First, the PoS difficulty is
supposed to be much, much lower than the PoW difficulty in a PoW/PoS coin. That's by design and is part of the source code. The reason is that the likelihood that a stake will qualify for minting is based entirely on coin age. Once qualified, the low PoS difficulty allows the stake miner to find a hash with very few resources and within the target block time.
Second, all of the attacks suffered by PoW/PoS coins are directed at the PoW component. EBT is a case in point. Just read the summary above. In fact, if you read all the way through, you'll see that to get the servers synchronized, they use the blockchain kept by the PoS minters. Proof of this fact can be seen by the long stretches of PoS blocks.
Finally, if you read the entire Blade thread, the Blade APR is 20.19%, in line with the Bladerunner theme of the coin, not 100%. It looks like someone on the Balde team needs to update the OP.
I have full and better understand of PoS coins than you, and I very well know how PoS works..
The low difficulty suggest --
You need to run a full node in order for the wallet to mine blocks based on PoS and it should be up always; how many people will do that? (especially when the interest rate is low)? When these coins will be made popular, 90% people will run light weight wallets giving power to the hands of these 10% (PoS difficulty will be low in this case).
Difficulty of 10 for the 3rd largest cryptocurrenty is very less. And I bet most of the contributers of the difficulty are the exchanges.
It's all in the FAQ, it's you who failed to read. And the reason why I made up that article is exactly for people like you and I've proved my point over and over again 10s of times, you're not the 1st one.
For e.g.
this guy (just like you) claimed that Bitcoin is the best crypto. He's living in a cocoon like yours and you, like him, will end the debate blaming me instead of cutting the facts that I put here. Besides your task here is to protect your hard earned 5-minute block target crypto (30 minute confirmation!) and targeting everyone who targets your beloved coin which has horrible specs.
Failure of PoW in this coin can be entirely be blamed on the design flaws of this coin. More than 90% of successful cryptos, especially the new ones are PoW and there are many simple and effective difficulty algo to protect against just that (multipools i.e.) and they're targeted by them all the time and none of them stop. All have learnt. This crypto doesn't even specify it's difficulty re-target algorithm, and the dev refused to fix it.
As of 20% rate of return --
Stability in prices -- Cryptocurrencies are not commodities. It's designed to be spent and a medium to receive payments from. If a cryptocurrency is not that, it's basically a pump and dump scheme.
Actually if you see for a fair cryptocurrency which is not seen as an investment, there should be a little bit inflation, cause that way people will not hold on to it like investment; instead they'll use it to buy investments like shares and gold -- which is something to be seen as an investment.
And this one has
20% inflation. Once stability has been established, it's prices will drop 20% each year if all the coins are online, and cause of it's high interest rate and design (100% PoS) there are reasons for them to be online.
Proof of stake is not good.
It encourages holding the coins as investment, avoiding it's circulation, i.e. true use as a cryptocurrency. Then worst -- PoS looks at the coin age; the longer you're holding a large amount of cryptocurrency, the higher the chance of mining a block, which further reduces chance of circulation. However if the profits proof of stake is giving you is negligible, then we may nullify this disadvantage.
PoS is good, if done right and along with PoW.
