Could have bought it in March this year for sub $4000.
Not. If you expect the price of bitcoin to drop below $4000 then you are dreaming and I don't think your wish will come true. The price of bitcoin has broken records at the beginning of this year, even now the price of bitcoin continues to increase despite a decline a few weeks ago.
Anything could happen, and even when most of us foresee a bright end of year, price could drop for any reason (well, below $4.000 sounds too dramatic to be honest

)
Don't we all wear laser eyes until 100k?
