Anyone mentioning "Crave" in the same breath as Dash is doing a disservice to Dash.
Crave is NOT a copycat of Dash; it is a Proof of Stake coin.
Proof of Stake and other non-mineable coins like Crave, Shadow, Ripple, NXT, B*SharesX, etc. are ALL scams, by nature. What do I mean by scam? I mean there is nothing ensuring decentralization. Nothing you can trust. A coin with no mining is not even a coin or currency, in an economic sense. It is a non-trustable token of a "public" ledger; at any point it can be 51% attacked/coins stolen/manipulated (see the "nothing-at-stake" attack for technical specifics)
To basically understand why Proof of Stake coins are extremely risky investments, you should first delve into one of the fundamental ecomonic reasons of why real Proof of Work cryptocurrencies like Bitcoin are valuable in the first place.
The value is in the public blockchain that is at once not-fakeable, completely trustable, and decentralized. The thing that ensures these properties is the Proof of Work, which comes from real (not-fakeable) value invested in mining it, i.e. computational power and electricity.
Bitcoin is attractive as an investment because it can be trusted, and that in itself gives it value. That is the only reason Bitcoin has a multi-billion dollar market cap. Smart investors will continue diversivy into real cryptocurrencies like Bitcoin and Dash this because they are real and persistent commodities, like gold.
With a proof of stake coin, you must assume it is compromised. There is no way to ensure otherwise. A "blockchain," you say? An ostensibly public ledger with no mining behind it is not a blockchain in the true sense of Satoshi's invention. It is not a matter of if, but when someone decides to run away with the money (claiming hacks or whatever... there is no difference between a POS coin and GOX, mintpal, etc.). People are blindly trusting whoever is in control of the coin. That trolls constantly attemt to defame Dash as an instamine/centralized/scam coin speaks volumes to the fact that this is the only reality they actually know (the one where the developers and cohorts always hold all the cards (POS/ICO/2dayPOW/etc) and manipulate unsuspecting investors).
So back to Proof of Work. Let's use Dash as an example. Dash is a PoW coin with actual $ of hardware, electricity and effort put into the confirmation of the blockchain and creation of each coin. As explained above, people invest long term into such coins because they can trust that nobody is able control it and steal people's money. Add to that the masternode layer of 1000 coins that are trustable due to PoW, then you have real value (collateral) being put into the masternode network as incentive to provide services that give the individual coins themselves even more value due by increasing their fungibility, along with providing countless other services to keep the network healthy and efficent.
Now, say the PoW aspect of Dash did not exist, and the masternodes themselves would find blocks and be rewarded based solely on their 1000Dash collateral, plus the current affordable VPS specs required to maintain one. Now while it is true the VPS represents a modicum of real world value, you have now removed most of the coin's grounding in reality, or rather taken away the value of the coin which is agreed upon in non-crypto world (electricity, hardware power, effort, etc.). With this situation, you can no longer say that the collateral for the masternode network is trustable as value in the sense that you can for a another currency or commodity that is either widely trusted and government manipulated (fiat) or requires no trust (bitcoin).
What I'm getting at is that the only reason you can trust Dash masternodes is because there is PoW required to ensure the collateral is even worth anything. This whole "Crave" thing is an insult to Dash's truly two-tiered masternode+PoW system by comparison. While I feel sorry for anyone who gets suckered into buying that, SDC, XC, or any of the plethora of other POS coins, I also realize that most people don't take personal responsibility for their money and generally feel the need to entrust others with it, thus creating constant opportunities for scammers. It is a necessary step in the growing process when new freedoms are born.
Outstanding...
