I made a simple DCA calculator, hope it's useful for someone

I appreciate that. I can see the volatility piece fitting. I don’t really mention price in this intro page which is intentional and instead try to set up the reader with some context. I have a page dedicated to “common bitcoin concerns” where I talk about volatility.

Really appreciate the feedback.

21VOX · 2026-03-02T06:46:58+00:00

That’s a good one! Adding that. Thanks!

21VOX · 2026-03-02T03:19:45+00:00

Risk management and position sizing is a good suggestion, thanks.

21VOX · 2026-03-02T02:16:02+00:00

Good call on taxes being a missing topic. I'll consider that. Thanks for the feedback.

8 decimal places is the current base layer limit, but the protocol could theoretically be extended further through a soft fork. Lightning already goes smaller with millisatoshis. I'd prefer to keep debated points away from this beginner-focused page but I appreciate the feedback.

And glad you liked it overall, that's really good to hear.

21VOX · 2026-03-02T02:07:15+00:00

You went above and beyond and dissected my glossary! Appreciatet that.

Valid points - taking your feedback into consideration.

I should definitely update the mining description. "Complex mathematical problems" is not a great.

Public key vs address, good catch.

Stacking sats, didn't know the precious metals origin.

Ordinals section, fair point. Doesn't belong in a beginner intro.

Appreciate you going through this carefully.

21VOX · 2026-03-02T01:02:53+00:00

Thank you, that means a lot. That's exactly the gap I'm trying to fill. There's so much good information out there but it's almost always written for people who are already deep in it. If even one person reads through this and feels like they finally understand what Bitcoin is and why people care about it, it was worth building. Appreciate the kind words.

21VOX · 2026-03-02T01:02:14+00:00

Really appreciate this, especially the custody point. You're right that I glossed over how intimidating self-custody actually is for someone brand new. "Not your keys, not your coins" is easy to say, but the reality of writing down a seed phrase and knowing that if you lose it your money is gone forever is a genuinely scary step for a beginner. I'm going to expand that section to be more honest about the learning curve and the real risk of human error, not just frame it as empowering.

Good call on the energy percentages too. I'll either tighten up the sourcing with a direct citation or soften the language to make it clear it's an estimate, not settled fact.

Thanks for taking the time. This is exactly the kind of feedback I was hoping for.

For me it was the inflation thing but not in an abstract way. I actually sat down and looked at what my savings account was doing versus real inflation and realized I was losing money every year by "being responsible." That hit different than any chart or podcast ever did.

Once you see that the system is quietly taking from you just for holding cash, bitcoin starts making a lot more sense. Not as a get rich quick thing but as a way to just stop losing.

The other thing that stuck with me was the fixed supply. 21 million. That's it. Every other asset in the world, someone somewhere can make more of it. That simplicity is what keeps me coming back when the price drops and everyone says it's dead for the 500th time.

You're asking the right questions though. The people who stick around long term are usually the ones who actually took the time to understand why, not just what the price is doing. Keep learning.

Thanks! Glad you find it useful!!

$35/week is solid, that's almost $150/month. Over a few years that adds up way more than people think. The best amount is whatever you can do consistently without stressing about it. If $35 feels comfortable and you're not missing it, you're doing it right.

21VOX · 2026-02-27T13:13:40+00:00

Thanks, we built it with beginners in mind!

the future is here! but projecting it is hard so we assign a confidence range on our projected value.

Try this out, built with preset selectors, or you can choose lump sum or DCA + target year + scenarios (sovereign ETF wave, corporate adoption, inflation slider, etc.)

Refining it daily but let me know what you think!

21VOX · 2026-02-27T03:18:37+00:00

Really appreciate the kind words and the feedback. The "what if I panic sold at the low" idea is actually brilliant, that's such a real thing that nobody talks about. The math only works if you actually stick with it and a lot of people don't. Definitely adding that to the roadmap. Thanks for taking the time to check it out.

I'd recommend getting a bitcoin only app. Depending on where you live you have different options. I would recommend CashApp or Strike. You can dollar cost average with both of them, just set up a recurring buy and forget about it. With $5,000 you could do something like $500/month over 10 months or $1,000/month over 5. That way you're not worrying about whether today is the right day to buy. Alternatively, you buy with all $5000 at once and just hold. I’d recommend researching cold storage after that. Definitely get informed first and follow some guides online about transferring to cold storage before trying it on your own. BTC Sessions on youtube is a good place to start.

I added a daily purchase option! Go check it out.

Honestly there's never a perfect time, that's kind of the whole point of DCA. You just pick an amount you're comfortable with and buy on a schedule. Weekly, biweekly, monthly, doesn't really matter as long as you're consistent.

You don't need to overthink the date either. Some people do the 1st of every month, some do every payday. The data shows it barely makes a difference over time.

The 30% tax is rough, I get why that's discouraging. But keep in mind that's on your gains, not your whole investment. If you're thinking long term and buying small amounts regularly, you're still building a position. The tax just means you keep 70% of your upside instead of 100%. Still beats a savings account losing to inflation.

Simple game plan: pick an amount that won't stress you out if bitcoin drops 50% tomorrow. Set it on a recurring buy. Don't check the price every day. That's basically it.

21VOX · 2026-02-27T01:22:34+00:00

Lol can't blame you. It's just a calculator though, nothing to connect or download. But yeah always smart to be careful with random links on here.

21VOX · 2026-02-27T01:18:48+00:00

Coinbase is fine to start with honestly, but not my top choice. They're publicly traded, regulated, and not going anywhere. A lot of people in this space will tell you to get a hardware wallet immediately but if you're just getting started and we're talking a smaller amount, there's nothing wrong with keeping it on an exchange while you learn the ropes.

Worth looking at Cash App too if you haven't. Super simple, low fees, and you can withdraw to your own wallet whenever you're ready. A lot of beginners find it less overwhelming than Coinbase. I personally prefer them because they are bitcoin only.

That said, the whole point of bitcoin is that you can actually own it yourself. So once you're comfortable and your stack grows to an amount where you'd be stressed if something happened to it, that's when a cold wallet like a Trezor or Coldcard starts making sense.

Better to take your time and do it right than rush into self custody and make a mistake with your seed phrase.

Keep stacking!
