if you give me 10 bitcoins i will hold it for price increase because i know that very soon the price of bitcoin to reach to all time high level..
i will also hold all my bitcoins, in my opinion it will reach a new all time high really easily in the near future
Holding is the best and the safest way to earn bitcoins as holding doesn't involves any risk and even if price falls then you should not worry as it will surely go higher in future.
