I was going to suggest this too but Rikafip has (of course) already pointed it out. Don't all into the error of underestimating this advice, and not only when buying, but when sending also. A wrong address and you lose it; a virus that changes the address you just copied and pastes a different one and you lose it; not being careful when setting up the fees and you may lose it too (or a big part). It doesn't happen in a every day basis, but when it does, it can be devastating, moreover if you want to operate with 1BTC at these prices.
