By regulation I mean a mechanism that prevents the coin to pump or dump by $1000 over night. Keep the price relatively stabilized
and make gradual changes.
On one hand having a crazy fluctuation is great way to make a load of money, on the other hand it makes it very difficult for a retailer
or any company to employ cryptocurrency as a way of payment into their business and thus slows down or completely halts progress
in this area.
I think there's already enough pump-dump coins on the market where people make money. I doubt BTC will make it any further
in terms of daily usage, even though its price will go up due to high demand.
Just a thought...
Otherwise I am in, for starting a coin.
Market dictates the price. Based on the demand and offer the price will rise or fall. You can have extremely scarce coin with very high price that nobody can afford then the price would be less volatile but nobody will use that coin.
Price is not predictable nor subject of manipulation from within the coin code. Only market can drive this.
See the coins with little demand - there is very little volatility if price is sufficiently high. On other hand even large coins with high price suffer volatility.. Maybe emission curve could fix this - when price goes very high (no idea how this would be checked) the emission curve changes and there will be much more coins mined through next block.. Most people will want to sell them and make profit which will lead to increased offer and this lower price.
But they can also decide to keep it and in the end it's the same situation as before.
On other thought there may be a coin 100% owned by creator who emits the coin to the market to mitigate volatility. Something like central bank (which can be also distributed and holders can vote to buy/sell coins). When price go up, emitting new coins will lower the prices. When it falls, using income from initial emission can be used to bring it back. But that is heavy speculation and I think it would only work short term.
Volatility is not a problem when something has default price in crypto not in fiat. When a car costs 1 btc then it's always one btc. No volatility at all. But merchants use fiat and that's where volatility enters the big pictures. If they would be using only crypto there wouldn't be any volatility at all.
