Why am I inviting you to participate in Bitcoin Mastermind 2026? My first reason
Two years ago, I fell down the Bitcoin rabbit hole. Very quickly, I understood one thing: There is a huge amount to learn… and alone, it can take years.
But with the right network and the right method, you can dramatically accelerate your progress.
That's what motivated me to participate in the very first French-language Bitcoin conference: Bitcoin Mastermind.
My very first Bitcoin conference. And, without realizing it, one of the smartest decisions of my career.
There, I met:
-Bitcoiners who are already building, -entrepreneurs,
-curious individuals,
and above all… opportunities for collaboration.
I also discovered major players in Bitcoin education like Plan B Network and Btrust.
But the most striking thing?
👉 I didn't just leave with knowledge.
👉 I left with connections.
👉 And real collaborations.
I'm going back this year. And I sincerely hope you'll join me.
Tickets are on sale now. Get your PASS.
https://btcmastermind.xyz/tickets
See you down the deep Bitcoin rabbit hole. 🐇🧡

Day 30: Write and share five things you've learned from this challenge.
Hi everyone! I hope you're all doing well. A month ago, I came across @Confortdavidee's tweet announcing their participation in the #AprilChallenge organized by @BitKwa.
So, I decided to join the adventure. Over the past month, I've learned several things, five of which I'm going to share with you.
1) You never stop learning. Bitcoin is a recent technology that's evolving rapidly. It's therefore essential to stay informed.
With this in mind, Bitcoin Benin organizes two meetings per month: a meeting and a Bitdevs session. If you're in Benin, join us for the upcoming sessions.
In this spirit of learning, @africanbitcoiners is launching its first cohort of the Bitcoin Africa Academy.
Here's the link to participate: https://bitcoiners.africa/academie-bitcoin-afrique/
2) Bitcoin is a decentralized, censorship-resistant network powered by the currency bitcoin.
3) Forks will eventually disappear, but Bitcoin will last a long time. So, choose your investments wisely.
4) No one can stop Bitcoin.
5) We change Bitcoin more than we change them. Here are five lessons I learned during this challenge that I want to share with you.
Thank you to @BitKwa for this initiative.
Thank you to everyone who liked my posts.
A special thank you to @ProfEduStream who liked my posts from beginning to end.
Thank you to everyone who skips my posts. Thank you to my Bitcoin Benin community.

Day 26: What is BitKwa's mission?
BitKwa is a community exclusively dedicated to Bitcoin, based in Kwara State, Nigeria.
Its mission is to promote adoption, educate, and empower Bitcoin developers in Nigeria through Bitcoin projects.
See you tomorrow for the next challenge.

Day 25: What are your plans regarding the use of and engagement with Bitcoin?
Personally, I continue to learn about Bitcoin, because you never stop learning.
Bitcoin is a robust technology, and this is confirmed every day.
I actively participate in the Bitcoin circular economy in Benin.
I plan to:
- contribute to the growth of the Benin Bitcoin community by inviting new people to join.
- get involved in Bitcoin projects, whether technical or non-technical.
I also want to participate in Bitcoin conferences in Africa and around the world.
And above all… stack sats ⚡.
See you tomorrow for the next challenge. #AprilChallenge #KeepLearningBitcoin #KeepSharing #KeepGrowing

Day 23: What can we say about the Lightning Network?
What if you could send bitcoins to the other side of the world in less than a second for just a few cents?
That's exactly what the Lightning Network makes possible.
The Lightning Network is a Layer 2 payment channel network built on top of the Bitcoin network. It aims to enable instant and, above all, low-cost transactions.
As you already know, it takes about 10 minutes for a Bitcoin transaction to be confirmed on the blockchain.
This isn't very convenient when you want to pay for a coffee, settle a bill, or send money quickly. Furthermore, fees can become very high during periods of high network activity. That's precisely where the Lightning Network comes in.
The Lightning Network transforms Bitcoin into a fast, accessible, and borderless everyday payment tool.

Day 22: What is the value of the bitcoins you hold?
Today, we're being asked something extraordinary 😀.
As of today, I own 630 sats worth 273 CFA francs. That's all, but feel free to share 😁.
The wallet I use is @Mannabitcoin. You hold your own private key.
You can find all the information you need at 👇 mannabitcoin.com
In any case, challenge accepted ✅.

Day 19: What is a Bitcoin wallet? Give some examples.
A Bitcoin wallet is software or an application that allows you to receive, send, and store the private key that grants access to your bitcoins.
It generally includes a public key, which allows you to receive bitcoins, and a private key, which grants access to the bitcoins and signs transactions. There are several Bitcoin wallets available. Some examples include @cakewallet, @mannabitcoin, @Blink, @walletofsatoshi, @Trezor, and many others.
In the coming days, we will look at the different types of wallets that exist.
"Not your keys, not your bitcoins." Remember this golden rule.
That's all for today. See you tomorrow for the next challenge.
Tell me in the comments which wallet you use and why.

Day 18: Why Was Bitcoin Designed to Have a Limited Supply?
Hi everyone. I hope you're all doing well. Today, I'm going to answer the question of why Bitcoin has a limited supply.
For a currency to fulfill its role properly, it must meet several essential criteria: it must be exchangeable, divisible, verifiable, portable... and scarce. It's this last criterion that fiat currencies like the dollar, the euro, the CFA franc, and others have gradually abandoned because central banks print banknotes at will, especially during times of crisis. The result: more banknotes in circulation, and less money is worth. This is the mechanism of inflation: your money silently loses value while the cost of living increases.
To address this dysfunction in the traditional system, Satoshi Nakamoto enshrined in Bitcoin's source code a limited supply of 21 million:
-to make the currency deflationary,
-to make monetary policy predictable,
-to protect purchasing power,
-to preserve the inherent value of what one actually owns.
Satoshi also implemented a mechanism called the Halving, whereby approximately every four years, the reward for miners who secure the network is halved, progressively slowing the creation of new bitcoins until the last one is mined around 2140. That's all for today.

Day 15: Can money exist without banks?
Explain.
I think money can exist without banks. In ancient civilizations, banks didn't exist, but forms of money were already in use: seashells, salt, precious metals, and gold and silver coins.
Banks appeared later to solve practical problems: securing gold, facilitating remote payments, and issuing receipts for exchanged transactions. Over time, these receipts became money, giving rise to fiat currencies.
Therefore, money can exist without banks. Bitcoin is proof of this: a solid currency that operates without banking intermediaries. Today, we can send and receive value across the globe without going through a bank, thanks to Bitcoin.

Day 8: What are BitKwa's core values?
Hello everyone. I hope you're all doing well. As I mentioned, I don't know the BitKwa community very well, so I'll talk about Bitcoin Benin.
I'm convinced there isn't a big difference between the two communities; we share a common interest in Bitcoin education.
At Bitcoin Benin, we only talk about Bitcoin, about Bitcoin applications and innovations that can lead us to hyperbitcoinization, not crypto. "No shitcoins onside."

Day 6: How Does a Bitcoin Transaction Work?
Hi everyone, I hope you're doing well. I'll explain in very simple terms how a Bitcoin transaction works.
When you send bitcoins (money) to a friend or family member, you sign this instruction with your private key to prove that the instruction comes from you. Then, this instruction is shared and broadcast on the Bitcoin network. The network's computers verify that you actually have these funds and that they haven't already been used. Once verified, the transaction is grouped with other transactions into a block. To validate this block, miners must find a random number which, combined with the block's data, produces a result that meets certain conditions; it's a matter of luck and computing power.
This validated block is then added to the blockchain. The transaction becomes irreversible.
After a few confirmations (3 to 6), your friend or family member happily receives their bitcoins 🤩.
That's all for today. See you tomorrow for the next challenge.
