Crypto arbitrage in Spain: how it's taxed

Each arbitrage cycle: Buy low → transfer (not taxable, same owner) → sell high = capital gain

Example: Buy BTC at €58,000, sell at €58,200 → €200 capital gain (minus fees)

HFT bots: Thousands of daily operations, each taxable. FIFO global (across all exchanges) applies.

kointax imports all exchanges simultaneously, applies correct global FIFO, and generates consolidated tax reports.
