Tax Question: HODL vs Trader vs MIX (FIFO vs LIFO vs HIFO) (Tax method: Single vs Multiple depot)

Hello,

I’ve read through the FAQ’s about taxes but am still a bit unclear about the folllowing:

2 Questions regarding taxes:

1) The best recommended tax disposable methods (FIFO vs LIFO vs HIFO) if you’re a HODLER VS a leveraged trader VS MIXED

Example:

HODLER: Which is a smarter method that will save you more in taxes? FIFO vs LIFO vs HIFO

LEVERAGED TRADER: Which is a better method that will save you more in taxes? FIFO vs LIFO vs HIFO

**MIXED: **
if you’re holding 80% of your assets long term but leverage trading the 20% of your asset) Which is a better method if this is the case? FIFO vs LIFO vs HIFO

2) Tax method: Single vs Multiple depot

What are the advantages and disadvantages for these two?
And If you’re a HODLER VS a leveraged trader VS MIXED, which method is better or which one is more recommended to save more on taxes?

Thanks in advance everyone.
