It has been very hard to win "just hold" tactic to this day, but the thing is risk management. It's very hard to predict what is going to happen and it may be wise to sell if the trend might turn, you just have to buy back soon if the trend didn't turned. You may end up losing little coins, but someday the trend will turn and then you win a lot of coins/fiat if you always remembered to pay the "insurance".
