I rolled all my projects in to a single Github, though the foocoin github *should forward you. Here's a direct link:

I'm no expert in the nitty gritty of these difficulty algos, but I hate it when there is a new coin and big miners jump on it to mine when the difficulty is still very low and then after a few acquired millions they leave to pump-and-dump their coins leaving the real supporters of the coin facing high difficulty! 
I think that difficulty retargeting (or balancing) should be incorporated so when the big hashers leave, the difficulty level will balance itself with the remaining hashes - kind of 'supply-demand' ideology. What I mean is that if there is high hashrate = high difficulty; if small hash rate = lower difficulty. IMO this is a needed component for the longevity of the coin to remain in existence.

Now as for the value of the coin, if we look at the real world examples, there's no fiat currency that has its value based on its scarcity (as far as I know). Yes there are other things like diamonds, gold etc. that their value is based on that, but in this case I'm treating 'the coin' as the main currency. So the value of the coin has to come from 'the need to be used'. This you are already taking care of as you mentioned many service where it can be used. One important service is an exchange, although I personally do not agree with the exchange of crypto-currencies to fiat-currencies as it completely defeats the purpose of cryptography, as once it's translated into a fiat currency it becomes traceable  now that's my opinion and a completely different argument. But it seems that the community wants this and so it be...

One thing I haven't seen in the announcement is the total amount of coins. Do you have an idea how much you're going to make it?
I might be dumb as I cannot understand why devs make hard caps and limits for their coins. Is every coin designed for a few number of years only? Why is this? No one envisage their coin being used 20, 50 years from now? Many might argue that it is so because Bitcoin is like that... right, but was bitcoin designed to be an 'eternal' currency or was it an experimental idea that a genius (or a group) came out with and wanted to see if it is possible or not, so it was coded with a cap for that reason? I don't know of any fiat-currency designed for 5 years only for example and thus, coins should be modeled or successful real world fiat-currencies (without the bureaucracy of banks which is taken care by the network and blockchain) ... And I'd like to see what happens when most coins reach their caps and they might become useless and just history... I might be wrong, but as I said, I just can't understand this point.
Anyway, I'm mentioning this so you might research a bit on these ideas / questions and see if there is any way you can increase the longevity of the coin. Maybe this coin can be unique as I'll be able to pass down to my children and they to theirs 

I respect the name choice as I completely understand your thinking and intentions, but having a person's name as the name of a coin is a bit unappealing (at least for me) and could be open for various interpretations as everyone has different points of view. In fact there's already a post about 'radiation' and even I when I read the name thought that this might be some radiating coin that has some features that reflect this. But as you said, you named it like that for her achievements and hard work...

I'd rather go for an adjective or something symbolic as a name for the coin that portrays Marie Curi's achievements and your line of thought - might be more catchy and acceptable. Although as you both said, MCC is quite good.

Now, apart from the name, I think these are a couple of points that you should consider:

• do not offer instant bounties for pools - I don't know how many coins failed because pool owners took the bounty to create the first few pools and then jumped on the next coin, taking down the previous pool just to take again the bounties. If you offer bounties make them 'per month running' and not all at one go at the creation time;
• I'm not favorable to the idea of always increasing difficulty. Many on here are armed to the teeth with pro mining rigs and can kick the difficult high quite fast. This would deter small-hash miners to keep supporting the network in the long run and would definitely be unattractive to newbies joining the crypto-world to support it too, as most also would have small-hash power.
  

For now this is what I think should be considered, along with the good points many have already mentioned in this thread.

Thanks though for trying to innovate and listening to the community. 

In my opnion, the only thing that makes a coin legitimate is if it has use or not. This is what any coin should focus on. Mainstream doesn't care about innovation, mainstream doesn't care about pre-mines.
They don't understand, all they want is something they can use to make or save money.

Here's another contribution of mine ; make the name of short. Pronounceable. Try saying "MarieCurieCoin" a few times in a row. Do you think it'll catch on ?

Not to poo poo on anything here - this sounds very well intentioned - but I find the coin name to be very odd and rather random.

Why will it be named that? A good name is very important to a coin's longevity.
