Taking those "worthless" coins that are less than $1 is like a gamble if you will wait for its pump and expecting a x100 return. I'm experiencing a problem when doing this strategy of buying those super cheap coins. I did invested to PAC and bought hundred thousands of it even it pumps a single sat no one wants to buy it. And that's why when choosing those "worthless" coins make sure that there's a good trading volume on it daily. I have two coins that are just for holding and waiting for it's pump. And those coins are DGB and siacoin.
