Your account was created on January and from January till June is six months now and ever since then I don't know if you have been active in the forum or not and you just made this post recently, I think this could be the reason why you're finding it hard to understand because had it mean you have been active this past six months I'm pretty sure that you would have been familiar with some certain things, if not having the basic knowledge about Bitcoin investment. So since you're just starting you don't need to be in a hurry, all you need do is to take your time to read threads from those high rank members  about Bitcoin investment, or better still you can also look into those links that is been provided here.
