throwing random numbers is always easy. analyzing and giving a proper speculation is hard.
what you are doing here is making a random guess based on literary nothing and your topic is so far worthless because of that.
as for "preparing for the worst", you seem to be forgetting that this current price is after a huge 80% drop. this IS the worst and even if price by any luck goes any lower it still doesn't make the current price a bad entry point.
You are right, this decline is the worst, it can be even worse, but I have no doubt about the time when Bitcoin can grow higher than before. I think at this point bitcoin is still able to survive at 3k until mid-year, most likely there will be no high growth this year. I think maybe 2020 is the time to start buying
