That is a lot of money to invest into Bitcoin. The first thing you have to decide whether you really want to invest into Bitcoin and for what reason you are doing it. If you are trying to spend it, then there really isn't much use in buying Bitcoin unless you want to be anonymous online. If you want to invest into Bitcoin for storage purposes, i.e waiting for the price to rise, then now is a pretty good time to purchase Bitcoin because the price is quite steadily rising.
