If you buy Bitcoin (BTC) $BTC for $30 (conditionally — “USD”) once a week, you are applying a strategy called DCA (Dollar-Cost Averaging) — averaging the cost in dollars.

Here’s what it means and what the consequences may be:

📌 What is DCA and how does it work?

• You regularly buy BTC regardless of the current price.

• This helps smooth out volatility: sometimes you buy high, sometimes low, but on average — at a “fair” price.

• No need to catch the perfect moment to enter the market.

📈 Pros:

1. Lower risk of loss in a volatile market.

If the price “jumps” significantly, the average entry price will be more stable than if you buy at the peak.

2. Psychological simplicity.

You don't worry about the rate — just buy regularly.

3. Effective in the long term.

Historically, BTC has grown in the long term. DCA allows you to “capture” the growth.

📉 Cons:

1. Lower profit during growth.

If BTC rises sharply after one of the first contributions, you will not have much bought cheaply.

2. No guarantee of profit.

If BTC falls for a long time or does not grow, your portfolio may be in the red.

💰 Example (roughly):

• If you buy $30/week = ~$120/month.

• In a year: $30 × 52 weeks = $1,560.

• If BTC increases, for example, by 50% in a year, you will receive $2,340 (roughly, without considering fees and exact dynamics).

📊 Real case:

DCA in BTC $BTC

over the last 5 years (at $30/week) has yielded several times more than invested, especially if not sold during dips.

✅ Conclusion:

Yes, this is a good strategy, especially for beginners and for those who do not want or cannot constantly monitor the market. If BTC continues long-term growth, regular purchases even in small amounts — this is a sensible approach.
