In Bitcoin, every feature serves to a particular purpose. In these coins every new "feature" serves the only one: attract newcomers to the coin. Let's have a look:

1) Masternode one click setup.

In DASH masternodes serve to the network providing a lot of functions. Some of them are: InstantSend, PrivateSend, Governance. These services are necessary to work 24/7/365, and masternodes are paid for these services.

In CropPay (and most of other clones) masternodes are only way to earn money. They still can do PrivateSend and InstantSend. but Governance is not used (and even does not exist in that old code). Many people know what the Dash Governance is? Masternode operators VOTE for independent developers offers and if most voted for a feature, the originator of request is paid by a network without any airdrops or gifts. This means that masternode operators should vote. How many people who use "one click setup" will do that? How does it help to network?

2) Tiered masternodes.

They have no service to the network at all. They only provide undefined emission since no one knows how many of each kind will exist. Do you think that random emission is good for a coin? They only serve to make entrance cheaper. But this is only to make money, not to provide network services including governance.

3) HODLbank.

There are other coins which introduce it. One example is PegasCoin with its DOB (Deposits On Blockchain), where you can freeze some amount for some fixed time, and get interest on that. But PGC has a lot of code to provide that. There is no any real use to the network from that feature. It is almost the same as staked coins, where you can stop it at any time.

It was said that CROP has a kind of escrow address where most dev premined coins were held. As you see, there is no any support for escrow in the code, and there is nothing which prevented full dump of that address.

4) Undefined emission.

The only one way to change it is to change the code and make a fork. This way was tested on CROP when after 20 coins it was raised to 100, then changed again. It was said that "community will vote for best rewards". But when was time to release, and many (including me) asked "when will we vote for it", the answer from cropdev was: "We set the best rewards", and no any vote was conducted.

So the only way to change it is the arbitrary decision of one person, the "dev". Do you think it will help to make a coin popular when at any time you may find it was forked a week ago and all your latest coins are not spendable? That exactly what happened with many CROP holders. Do you think Bitcoin was so popular if it changed blockchain parameters once a week or month?

ALL THESE tricks are to attract people who wants to make money. In that case the CropPay is the best of most shitcoins around. But if you think these coins may be used for long term investment, you are blind.
