Hm. I also went into it without knowing a lot. I think the biggest point to make (after, of course, don't risk money you can't afford to lose) is: never settle for a loss. If you buy a coin and it goes down, hold until it's up. Never panic sell. If you manage to buy in at a low point, and you sell for a bit higher, don't buy again until it's lower than what you sold for. Then, at least, even if you don't win big, at least you can't lose big. I managed to buy a few LTC at 25 and sold them at 39. So I'm happy to be ahead. And if it doesn't go below 40 again, well, it was a fun experiment. But if it does, I'll buy again, and ride them for a while.
