You'lll never be able to time the absolute bottom

[Torque]

.... so quit trying.

Ask yourself this simple question:

Do I think that the price will be a good bit higher at the end of the 2015 year, than it is right now (~$220)?  

If the answer is 'yes', then just buy now and forget about it and hold until then.  Whatever happens between now and December, don't even care.

If the answer is 'no', then don't buy.  

It's that simple.  Most long investors think in terms of at least > 24-36 months minimum.  If you are gauging on a timescale lesser than 12 months, then you don't know how to go long on anything in your life.  You are just a shit newb investor that will never learn, that is all.

Discuss.

Absolutely legit. Trying to buy 100 up or down is a waste of time to any decent investor which should think low term. You are risking more by trying to find the perfect buy entry because you can miss the train.

Also trading on margin is extremely dangerous at these low prices because of manipulation. You will get margin called!

If you are good, you can always trade to acqire more coins, but think of the practical problem of getting your billion into and out of the exchange and into cold storage. It's a full time job!

Generally the traders advise you to wait until you are certain the bottom is in before you buy.
