I have been interested in bitcoin for a few months, and bought a coin or two before, but ended up withdrawing it all back into cash. Went away for a little while and didn't even think of bitcoin for a little while and looked it up to see it was now $400... Watched it rise, and rise... And Now I find myself wanting to kick my own !!!!!!!!!!! for not buying more (and keeping them).

But since I'm in this for the long run, and not to make a quick profit, I'm not looking at the current ~$1,131 value of one coin as a bad thing, because I thought it would rise this high when I first looked into it...

So now I'm stuck here deciding... Either buy into btc now (I have ~$1,400 that I can invest safely)... or wait and hope for a price drop...

What are your opinions? And whats a good way to ensure I can get a good deal? i.e. say it drops $100 or so in a day for a few minutes...? How do I make sure I can get that price before it quickly jumps back up? I'm currently looking for a program or website that will make a noise or something if it drops to or below a certain point lol
But how can I have the money already deposited somewhere so that all I have to do is press the button to buy? I know localbitcoins, but is there anything else trusted?

Thanks to anyone who reads this and helps
