Question 1

What is the difference between FIFO and LIFO?

Accepted Answer

FIFO (first-in-first-out) sells your oldest coins first; LIFO (last-in-first-out) sells your newest first. Because the lots were bought at different prices, the method changes your cost basis and therefore the taxable gain on the same sale.

Question 2

Which method should I use for crypto taxes?

Accepted Answer

It depends on your jurisdiction — many require FIFO, some allow specific-identification or LIFO. In a rising market LIFO often defers tax by matching a higher recent cost basis, but you must use a method your tax authority permits and apply it consistently.
