I depend on what you are doing with bitcoin. If you're investing in it, then yes. Because you need to maximize the price of bitcoin to get a profit in investing in it. However, if you are just exchanging bitcoins and buying stuff after, then you don't need to mind the price.
You don't need to worry about the price if you are exchanging fiat to bitcoin in order to buy something but if you are exchanging bitcoins to fiat in order to buy something then price is everything that matters, because if the price is low you will get a lower exchange offer which would not be liked by anyone.
Price matters most in trades and exchanges. People prefer to sell at a higher price than buy which is obviously at a lower price. The price is the main attraction for the traders who trade on the market everyday.
However bitcoin shops and stores prefer the more stable price and people prefer to buy bitcoin at lower price as well.
yes, the traders only want the high price for bitcoin and they will sold their bitcoin to get profit and this is why the price of bitcoin is really important for us. with the price for now, i think the trader will wait for a little time and they will hold it or just put some satoshi to trade with altcoins and make their bitcoin growth and if the time is come, they just sold their stock of bitcoin.
