we really need LN.
As far as I know, people are testing LN already, I have seen someone to give loan with LN here on the forum for experimental purpose only. So, we can expect it to be fully used near future.
This is going to be the future but before that let the prices be a little stable as no one will spend their coins unless they are sure that the prices won't increase in the near future.
The price will never be stable, even if it gets accepted widely and everyone uses it. It's not anymore the way of convenient of a transaction, it's an investment opportunity now.
