For those looking to enter the cryptocurrency market with a starting capital of $100, the process begins with selecting a reputable centralized exchange. These platforms act as intermediaries, allowing users to convert fiat currency—such as U.S. dollars—into digital assets like Bitcoin or Ethereum. Experts emphasize the importance of choosing platforms that prioritize security, such as those offering two-factor authentication and cold storage for assets.

Once an account is created and identity verification is completed, users can deposit their funds via bank transfer or debit card. A common strategy for small-scale investors is 'dollar-cost averaging,' which involves investing the $100 in smaller increments over time rather than all at once. This approach is intended to mitigate the impact of market volatility. After the funds are deposited, the user can navigate the platform’s interface to select a specific cryptocurrency and place a 'market order' to buy at the current price or a 'limit order' to buy at a specific price point.

Security remains a primary concern for new investors. While exchanges provide custodial wallets, many analysts suggest that for long-term holding, moving assets to a personal, non-custodial 'cold' wallet provides greater control and protection against exchange-level hacks. The entry process is designed to be user-friendly, but it requires a basic understanding of transaction fees, which can vary significantly between platforms and may consume a portion of a smaller $100 investment.
