Holding is like sniper waiting to pull the trigger, you know that there so may people blocking your target's view but you need to wait patiently to shoot him, sometime people pull the trigger on early bases so they failed on their assassination because they hit the shoulder, the ear, stomach, not the heart or head. Same like bitcoin, if you get my point my friend.
Yes hold it dont panic if the value was decreasing do not go unto panic selling because you will lose all your investment, ask or research what to do in decreasing coins if you're new to this investment, i rather choose to hold coins and invest if increasing.
