However, with DCA, you spread that $20,000 across five equal $4,000 purchases, resulting in costs of $20,000/BTC, $15,000/BTC, $5,000/BTC, $5,000/BTC, and $25,000/BTC. This approach yields an average cost basis of $18,000, and you'd have 2.3 Bitcoin. When Bitcoin's price eventually rises, your gains can be amplified because you lowered the average cost of acquiring your holdings. With DCA, you steadily accumulate more Bitcoin, even during market ups and downs.
