You do realize that LTC, XMR, and ETH have VERY different cases for use, right?  Lol ... I don't think you have researched anything other than the fucking current value of each coin. 

I haven't said this to anyone in awhile.  Start reading this forum, legit crypto news sites, listening to podcasts.  Don't stop until your eyes are bloodshot and/or you fall asleep (8 hours/day min).  Do that for about 90 days straight.  You'll thank yourself for it later.
