Minimum purchase amount
Bitcoin is divisible into 100 million satoshis (1 satoshi = 0.00000001 BTC), so you don't need to buy a whole coin. Most exchanges have a minimum order of $1–10.
Bank transfers are usually fee-free from as little as a few dollars. Card or instant payment methods on exchanges like Bybit or Bitget typically have a minimum of $20–50.
Practical tip: start with $50–100 to go through the full process (verification, deposit, purchase) without risking a larger amount.
How much to invest realistically
First purchase: $100–1,000, to learn the full process.
Ongoing plan: DCA of $50–150 per month – this averages your purchase price and removes the stress of timing the market.
Portfolio allocation: 5–10% in crypto for a conservative strategy, 20–30% for an aggressive one. The rest in stocks (S&P 500 or MSCI World index funds), bonds, and real estate.
Golden rule: never invest money whose loss would affect your financial stability. Crypto has fallen around 80% during past bear markets (2018, 2022).
The DCA strategy
Dollar-Cost Averaging (DCA) means buying a fixed amount at regular intervals, weekly or monthly, regardless of price.
Simulation: $25/week into BTC from 2020 to 2024 — total invested around $5,200, ending value roughly $20,000 (CAGR around 40%).
The simplest setup: an automatic bank transfer each week plus a recurring BTC/ETH purchase – most exchanges offer an 'Auto-Invest' feature.
Summary
The minimum order on crypto exchanges is just a few dollars, but realistically start with $100–500 and spread your purchases over time with DCA. Keep crypto to around 5–10% of your investment portfolio.
