Its good to wait for its price to drop, but be sure that you wisely predicted the value change.. You should not stop buying bitcoin, the price is not yet to high. Its not too late to buy bitcoin, there is still promising future that awaits. There is no denying that it would be better to buy once price is lower that the current but sadly price is rising instead of dumping. So now, its still time to buy as much as we can afford, just look at bitcoin as ever growing aaset.
I love how everyone says "bitcoins" "buy Bitcoins", etc. when the reality of it is in today's world 99% of people can't afford to "buy bitcoins" and most people can't afford to even buy one, unless they take a big gamble with their life savings or something.
It is crazy to think how back in the day people made 35 or 50 Bitcoins per day from mining it on their laptops. Imagine making $200,000 ina day just from running a program on your laptop.
