There is.
If you go long term and don't look at the current market conditions. You'll only get hurt if you check the price from time to time and it won't go accordingly to your plan.
I doubt the capacity of oP to be able to hold via long term investing,because theres seems like he cannot help but checking the market prices from time to time lol
But mate was right,if can afford of holding for years,then for sure you can profit and gain enough for your investments
