Cost basis of Limited Partnership assets

There is a limited partnership (an LLC taxed as a partnership) that owns various assets.

If I buy interests in the partnership from existing limited partners at an arbitrary price, how is the cost basis of the assets computed.

For example, lets say it owned:

1 Oz of Gold worth $1887 at time of writing but acquired 5 years ago for $1300

2 shares of Tesla worth $663 at time of writing but acquired 5 years ago for $38 pre-split

1 Bitcoin worth $26,000 at time of writing but acquired less than one year ago (9 months) for $5500

This has a total value of $29,213.

and I bought 100% of the LP at a premium for $30,000, which has no revenue or debt or additional intellectual property. Assume I just like the name of the LP and that myself and all relevant parties agreed to a price ?‍♂️ so we can all just focus on the real question:

What is my cost basis of the LP’s assets?

For example, do I inherit the cost basis of the gold’s $1300 purchase price and long term capital rates?
