Trying to time the best entry point into altcoins has been a disaster for many in the last month or two, especially. It's one thing for an altcoin to beat USD but it's turned out to be quite another to beat btc the way that it's been rising. Some seem really good at it, but I think we hear more of the success stories and less of the majority who lose money essentially betting against bitcoin. Buying an altcoin is essentially like saying you think it's better and will be more popular and more valuable than the coin with the most devs, the most publicity, and the longest track record. Kudos to those who can do that, but I think most try and fail...and are too embarrassed to admit it. I've seen coins that I read about, learned about, and really believed in drop to 1/3 of their IPO...in fact, that seems to happen fairly often. It's a risky game..
