Holding is the best strategy we can exert with price drops in the
cryptocurrency market. If it’s all about long term investments price
drops wouldn’t affect your mindset towards holding on and selling
altcoins in the future. But selling them if you need then money at
moment is also justifiable, each and everyone of us has different
purposes and reasons getting into crypto. As long as it helps and
favors our needs and wants I see nothing wrong with holding or
selling altcoins in evey market situations.
