If I am still very confident that bitcoin will go back up so holding an asset in the long period is increasingly opening up opportunities in gaining substantial profit in the future especially to invest in bitcoin.
Holding our bitcoin to hopes for the great earnings is good because we have our own strategies. Most who holds are confident indeed that price can increase. So holding can be good since most of us are much aware about volatility of bitcoin price.
Holding bitcoin is not only for the hope of earning good but most of us do only hold bitcoin in order to use for spending and for other payment purposes like for example when doing online shopping or for paying their bills , buying mobile recharge ,etc. You know bitcoin is not only an asset because bitcoins main purpose is actually for paying. Therfor i think hodling or investing is not actually a strategy but rather it is only a normal act or way of using bitcoin.
