Crypto: Still a good idea?

There are a lot of coins floating around. Not all of then are good, but not all of them are bad. You've really got to do your research on anything you plan to invest in. Crypto currencies are no exceptions. I've personally made a few hundred through the major ones. That was just through small investments that grew over time. I started with smaller amounts across a few coins, some inflated heavily and a few other dropped. I just sell when I go over 20% and wait on my other ones to balance out or turn a profit later on. Sometime I get real lucky and cash out at 50+% but that's more rare unless the coin is unstable.
