I am a new user of this, still learning on how it works and not sure how to start buying.
Now, just after the drop, will be a good time?
Yes when the price of bitcoin was low it is the prefect time to buy, and wait till the price goes up, but still it is depend on your judgement, if you feel that the price of bitcoin was perfect for you to buy then go, and when you feel that it is the right time to sell your coin which can give you a chance to earn then sell it.
