This is more less concern to me because I trade almost everyday and holding is not a choice but I only make sure this time holding is more than investing so at this time it brings more profit.
Sometime we are afraid if we sell early our coins because of low price in the market.
But for me if the coins we receive comes from bounty must better to sell it early and they are have a time can going down quickly.
It would be better to buy a lot more coins. by having more coins will be able to generate more profits in the future which allows it to become the main source of profit who can afford to continue to rise again in the future.
