After focusing on XRP and XMR for the last few days my XMR finally sold at the desired price last night while sleeping (too bad I set the limit at 0.016 but up till 0.017). And I'm holding on to my XRP for a bit more since I bought in way too high and then the drop came. So I'm holding on to that till it at least breaks even again.

But now I thought what coin should I look into next, went to EthereumWisdom, everything is green and I'm a bit at loss which coin shows some potential to fluctuate a bit.
So my question is, which coins are worth keeping a eye on and any warnings about certain coins that might be traps?

I understand that no one can predict the future so that's why I'm asking only what coin to keep an eye on and possible traps.
Also is there any free platform that analyzes historical data and offers possible trade opportunities? I was thinking about making something like that myself but if it already exists I'd like to use that in the meantime.
