I don't invest in most altcoins but I am heavily invested in Monero(XMR). Definitely look into it because I see no reason as to why it can't become at least valued for those who need the absolute privacy. Arrests have been happening and it is only a matter of time before the arrests are more common and people need the alternative.
Some people are betting on Dash shooting up but it's just a scam coin. If it does go up, sure you could make money, but I'm not wasting time with it. I don't think there is real potential for the coin because there are companies who rule them out since they know about the instamine and basically that it's a scam. Who knows if it will get pumped again, I'm not wasting my money on it though.
