If bitcoin value decreases just like what is happening now,i will avoid panic selling the coins i am holding and wait till the drop stabilizes then probably buy more coins. Bitcoin price dropping and then rebounding is a normal occurrence because of its high volativity. It also makes the market healthy and alive because it's a signal for experience investor and traders to add more coins to their portfolios. At this instances panic selling is not a choice as it will only add more losses to your investment and make the market unbalanced as it will cause an oversupply of coins.
