Bitcoin or Litecoin please help!

I wouldn't do LTC. The creator himself tweeted out saying that he supposedly sold all of his shares. It's gone down over 100 since the past week. It's just looking like a pump and dump in my opinion.

I would stick to Ripple. It's looking like the most practical ICO out there at the moment. Buy BTC, and transfer it over to an exchange where you can trade said BTC for XRP.
Hope that helps!
