These are the most likely coins to make a lot of quick money. What are you guys holding?
Where is your list or link? Seems missing on your post. For now, I am not really holding altcoins hoping that one day it will give me huge returns. I am still sticking to bitcoin. Whatever tokens I had, I converted already to btc. Because for me, btc will stay in the market while most of those altcoins will die and perish. A lot of them will be abandoned. So the assurance of getting huge returns will just be a dream. I really don't trust holding altcoins for long time. Just my opinion though.
thats really good decision if you already convert all your token to bitcoin, because bitcoin is the most promissing cryptocurrences
and for the OP i think you can find a good crypto under 50 million USD marketcap in this list,
