If you don't mind, I'd like to share a bit of unsolicited advice-

Don't trade altcoins solely as long term investments. If you're going to do this, at least include Bitcoin for a large portion of your portfolio. The fact of the matter is, on average, altcoins overtime will depreciate in value to nill. In general, they just aren't good long term investments to make. Beyond this, comparatively large or well known altcoins don't have the same explosion factor as the unknown shitcoins, but they both have the potential to die.

What I would suggest (and what many people seem to do here) is to start out with a small amount on Yobit or Poloniex and just play around for a while until you get a good grasp on the market as a whole. Once you've familiarized yourself with a number of coins, you can put larger amounts into coins you are personally bullish on- coins that have missions or communities you actually believe in. On top of this, you can do some day trading if you'd like.
