I am very new to all this but I have been looking at charts and reading articles almost constantly since December. There are definite trends emerging. I think the main problem is there are so many competing currencies and people are trying to jump on the next bandwagon.
It is a massive gamble.
The only people who made money in the American gold rush were the people who sold the shovels. And the people who provided the "entertainment".
Maybe these are areas where people need to look rather than the currency itself.

Though I know I have dabbled. In a very tiny way. Trying to spread the risk though. Litecoin went up then down, Bitcoin did the same only more extremely, Bitcoin Cash is still a bit volatile but less so.

Amusingly Dogecoin is the one that has given the most return so far! (Oh, and Steem, of course)
