I missed the dip the other day and am wondering if I should hold out for another dip or if the current prices are still decent. Mainly looking at litecoin and etherum. I also need coins regardless so I can exchange for other altcoins.

I appreciate all the responses. It has given me much to consider and think about.  One thing I'm having trouble with is dumping so much into bitcoin and not even having a full coin. I know I'm looking at this wrong and would like some differnt prospective from others.

Yeah 15k is alot to me but in the grand scheme of things and what others are investing it's a rather small amount. I feel like if I invested less I would regret it in the future.

 
I appreciate all the replies so far. I have to say initially I wasn't planning to put as much into bitcoin as most of you suggested. I was more interested in ethereum. It seems I need to do some more reading. As someone mentioned I don't know much about trading but am interested in learning. I would like to make some short term money once I get a better grasp on it all.

I'm looking to invest around 15k possibly up to 25k in bit and altcoins. Just curious how some of you would invest the money for the short and long term. I use to own some bitcoin a couple year's back but stupidly didn't see the bigger picture at that time. Trying to research as heavily as I can to get the best understanding of what's going on now. Look forward to hearing others opinions and reasoning for how they'd go about this.
