That's the beauty of the 10/200 method: it leaves the uncertainty out of the equation, reduces stress at lot and ensures you'll get a noticeable amount of money.

Recipe:
Will it go high?
- No, sell 100% at 107%
- Yes, sell 10% of your remaining stash every time it doubles.

So far, it worked quite well for me, too bad I had to loose almost 2000 euros before I realise it. I hope Monero will help me get some money back.

So, to sum it up: it is not "when to sell" but "will this coin go high?" and "what is the floor price?"

The floor price is less important. I you make a mistake, either you miss the train (you did not win, but you did not lose) or you hold the bag for long (like I did). But identifying if a coin will go high is much more important.
Here, I have not much solution. My double strategy (107% or 10/200) is the best I got so far. The rest is mostly luck/gamble/intuition, none of them being reliable tools.
For the moment, out of Cinni, I believe in Whitecoin (like Cinni, they suffered a lot and I am bagholding there too) and Monero (this one is easier: I mined it from day 1 and prices are skyrocketing from week 1 - plus it really is revolutionnary)

I hope this will help.

Oh, one more thing: beware of forum: FUD and enthousiasm will brainwash you. I was brainwashed on Blackcoin and a bit (but much less) brainwashed on Mintcoin. Keep a cool head, remember that most posters are governed by their testosterone and adrenaline. I you can't handle the stress (I cannot), simply avoid the forum altogether!

One last thing: I really like the "no more than 10k CINNI per wallet". Of course there will be abuses, but this still a good idea. Focus on trying to get as low a Gini index as possible.

Take care of my money
