I think buying at 30k$ isn't what I would do, I would have rather invested it into different coins other than putting it all in one crypto. With Elon Musk turning 180° on crypto, the future of a bull run seems dull to happen any soon. I am of the opinion that market will good down a lot more in the upcoming weeks.
Until recently, there was no reason for the parabolic run in bitcoin. There has always been a reason for dump like we see after elon musk tweets. Many are still hopeful as I am to reach new ATH above 100k before the end of the year. I dont rule out Elon Musk buying the dip and It is a reason to consider doing as well if fiat is available.
