I would also like to know which coins can bring me profit now. But it seems to me that such coins simply do not exist.
There are some good coins with low market value right now so if you invest in them for long term, and hold them without selling even a single coin, you would have a good chance to make money that otherwise is not so easy.
I think all coin thats listed on 100th cmc can easily go 3x because most of thats coin already drop 70-90 percent from its all time high. When the next bull market coming I believe thats coin can go easily 3x
