Not sure I get your questions, but here is what I can give you based on what I’ve understood from your OP:
- ICO success is not dependent on the number of tokens, Soft Cap or Hard Caps they set. In fact, there are Armageddon studies that rate ICO success on the whole very low (see
New Study: 80% of ICOs are Scams, Only 8% Reach an Exchange for example), with the following resulting distribution:
80% of the ICOs were scams from the start.
6% failed.
5% died in the process.
8% manages to reach the exchanges, but only half of them were successful.
- ICOs normally specify a fixed set of tokens on their whitepaper, with a certain distribution (reserved for personnel, pre-sale, crowd sale, promotion, etc.). The associated price may be tied to a FIAT value (i.e. 1 token = 0.2 USD) or cryptocurrency value (typically ETH, but there are others), and be defined beforehand or during ICO sale (i.e. Dutch Auction).
Some ICOs nevertheless alter the number of allocated tokens before the sale, especially if they have token value tied to FIAT and they want to change their caps. I can’t recall now cases that have risen the number of tokens to produce, but an example of the opposite can be found here:
nOS Significantly lowers Hard Cap & Token Supply.
If the case you are on about is increasing the ICO’s token pool, it is likely that they are rising their Caps (this could be good, since they have a better perspective, or bad if they rise it too much or is a scam to start with).
- Token value, as I said before, could vary before and during the ICO (even more so after), depending on how they fix the price as said above. For example, I’ve seen cases where the price is set against ETH, and ETH varies wildly throughout the ICO itself.
- Once the ICO is finished, if it manages to hit the markets at all, price will vary through supply and demand (and often due to pumps&dumps).
- When an ICO reaches Soft Cap, but not Hard Cap, it may decide (normally it should be in the whitepaper) to burn the non-sold tokens, which is generally beneficial for the token (of course, if it’s a crap token from a fraudulent ICO, it won’t really matter). Alternatively, they sometimes distribute the exceeding token amongst the ICO participants, proportionally to their contribution.
