With collecting, the hardest part is holding on to them if the price increases temporarily - keep holding & who knows how much profit you'll make. Buying crypto and selling at a slightly larger price is the hardest temptation to overcome.
This is true, you will never know if you will win or not if you are to gamble your hard earned BTC. And more likely if you are not that lucky, you will lose all of them.
Collecting is better and safer way to make your stash grow. You need a certain self restrain in order for you to accumulate succesfuly. We can see the tempation if the price increase to sell them but, having a goal for the maximum amount you need to collect before spending or encashinig them and the amount you will be encashing them is good.
