Off the bat, I'd like to point out that I've been mining CASH since day 3 (knew about it prior to launch, waited for any forking, dodgy launches etc..) and have been working to try and build the CASH community, however I'll be as unbiased as I can.
My opinions on BC and MINT are from what I've gleaned from the [ANN] OPs of each coin and a quick look at blocks/exchange rate etc.... Taken 75 minutes to look up info and type up this comment.
Also pointed in this direction by OP, who's promoting his own thread AND coin he's holding, with that lack of shame, could be corrupt banking CEO
EDIT: Was asked a little later what I mean by mBC / mMINT etc...
We currently talk about the price in bitcoin, but we'll talk in mBTCs (thousandths of a bitcoin).
Hence CASH will go from 0.0001 BTC to 0.1 mBTC, making it far easier to tell the price without mistakenly adding or losing a zero. $1 = 1mBTC rather than 0.0001BTC.
BlackCoin:
Rate of release during PoW is way too high, it's just putting all the coin in the hands of a few early miners, will cause a big dump and the PoS reward is too low to bother holding on to it which could well cause the blockchain to grind to a halt as only the exchanges will have the coins giving them some serious control over it.
The rapid hard limit will cause the coin to plummet in price as well.
Might not be 'pre-mine' but with that rate of release, being the first to mine will have been huge.
Good number of coins though, will hold off the need for an "mBC day" for quite some time, should the coin become popular enough to be facing it like bitcoin is at present.
Don't like it much though, but happy to hear constructive arguments to the contrary, there must be some as it's already hit 131 pages in 2 weeks, so pretty chatty community.
MINT:
Heard Mint being mentioned a fair bit by some names I respect in these 'ere parts.
Again, the PoW isn't near long enough IMO, but the PoS initial reward I do like, however I worry that an insufficient number of people will be holding MINT for the blockchain to work properly, the exchanges will end up holding the bulk of the coins and I can't see many bothering to mine it when there are billions of coins in circulation and they're only going to get 1 per block
Don't like random block reward coins and the total number of coins is just silly, (1 Billion is my prefered number for clarity) and the 1% pre-mine is fair enough. Helps to pay for the infrastructure to get things moving early on, there's certainly plenty going on with the coin
Again, the PoW seems very rushed and the fixed timing of it far too contrived, like the devs want to get BTC out of it very quickly then decide whether to stick around or bugger off to another project. I hope the cynic in me is wrong, I don't like selfishness!
Has potential, but it'll be up to the community to ensure the blockchain keeps ticking along or it could grind to halt like BC probably will. The high PoS reward should help to stave that off to an extent but only if people keep their wallets open continuously.
High risk coin with high reward for the earliest miners but whether it'll still function correctly after 6 weeks will be interesting to see.
CASH:
Love the variable block reward inversely tracking with difficulty to discourage mining and extend the PoW period when popularity picks up (max 30 coins per block down to 1 I THINK), this will keep the blockchain ticking along until the coins are well distributed and able to be sustained by the PoS.
The total coin count is too low IMO, will see an mCASH day far sooner than may be required, it does however keep the price from being in the single/double digit satoshi range which just attracts speculators, causing an even more volatile price than would happen anyway due to being an alt-coin.
The lack of pre-mine has caused issues getting an infrasture in place quickly to gain attention for the coin early. While this may prove profitable for us early miners, it also runs the risk of the coin being overlooked long enough for it to fade into the ether and become a dying/dead coin. The community behind CASH is therefore small with few members able to help develop it (getting on coinmarketcap for example has taken far longer than it really should).
The name is a great positive for it though, one of the few decent names and thankfully has good technology behind it. The Dev team, while quite are doing a good job resolving the very few technical issues that have arisen (the usual stuff) and has managed to not require or suffer a fork of any kind, which is always comforting to see.
1 minute block, 6 confirmations is par for the course for PoW and 25 for PoS is pretty quick and destruction of transaction fees should keep inflation in check and discourage mining in the medium term.
Conclusion:
BC looks like crap
MINT could be really good if the community can carry it through the transition from PoW to wide PoS adoption and not sell out to the speculators who will ravage the crap out of it and not give a monkey's if they kill it in the process.
CASH surprise, surprise has the most potential to remain stable through the short and medium term and the 1% targeted inflation per year should balance the loss of Private Keys.
I look forward to reading the posts of those who know BC and MINT better than I do, my opinion here isn't well informed on either of those and this message should therefore be ignored if researching them. If you bash CASH, I may add to the flooding here in the UK.
