More bitcoins will not hurt IMO, and any coin squeezed from the market is less available for traders and bears.
When grandmothers are using btc it is time to sell, and probably you do not even need to sell at that moment since the infrastructure has developed enough.
Well you have to wait for the 'right' time to buy, buying to high will get you in a mess. I am watching the market closely now, I do see the price touching on 550 which will trigger my buy orders on several exchanges.
The price could touch $550 again. I think I will hold my fiat and wait for the price to be around $550 before I buy.
The price won't touch $550 because the continued decrease in price has got paused. Now the price has been getting stabilized and today the increase has started.
We can't exactly the price's behavior in the future, but i'm ok with you that it will increase highly soon.
