The current price is looking sooo tempting

Should I go full in now, or wait for another dip? Or be rational and buy in 2-3-4 portions?

This is the question!

Wait. For sure.
Perhaps wait for sub $3k.
Why would you want to buy now? There has ONLY been less than a 50% correction from the $13,880 local high.
Actually, I am
all in in terms of life savings, but not in terms of networth, since I don't have a bank loan and I own my place and a car. Now I am tempted to take a loan from the bank guaranteed only by my state job salary and not by mortgage or anything like this. I've been playing various scenarios because a bank loan is a risky thing. What I've come
to as a solution is to take one loan to buy at the current levels with monthly payments for 10 years equal to 1/6 of my salary. The annual interest is 5%, so at the end is slightly above 25% for the whole period. I can't risk all money at once, since the price can fall to 3K. If this happens I can double the loan. I still have my cold stash which would be 3x-4x bigger than the loan and is an insurance against a theoretical job loss. I suppose the risk is not too big, since my state job is with an ulimited contract. My motive is not some greed for a quick profit, but rather to reach an amount in bitcoins which I had in my mind. I tried to reach it but I failed for various reasons. And most probably I won't reach it, because max 1 year after the halving the price will stay higher than 10K. If you want to encourage me (or not) go ahead, every opinion will be appreciated!
