Let’s go back to our website - the one where we watch our Bitcoin block tower in real time! 🧱 For creating an empty box, the miner receives 6.25 BTC at the current moment. 💡 This amount changes over time - it gets cut in half approximately every four years (a process called halving). 🧾 Total Fees - this is how much the miner earned from all the transactions packed into that block. 📦 The table also shows different box parameters, like: ⏱️ How long it took to find the block 📏 The size of the box (in bytes) 🧮 The number of transactions ✅ In other words: we see everything!

Questions, answered.
Anything else? Write to support@astratrainer.com and a person replies.
New to crypto?
Yes. The path starts with blockchains and nodes before moving into wallets, DeFi, project analysis, and portfolio rules.
Is this investment advice?
No. This direction teaches crypto concepts and decision frameworks. It offers no picks, predictions, or return claims, and it does not manage your money for you.
Must I understand code before I begin?
No. You do not need coding experience. The material explains networks, wallets, consensus, and tokenomics through the decisions a crypto participant faces.
Are wallet security and DeFi both covered?
Yes. You examine private keys and seed phrases, then trace DEX swaps and liquidity pool mechanics without funding a wallet as part of the training.
Will I earn a certificate after the final exam?
Yes. You earn a named certificate inside Astra Trainer after passing the final exam. The certificate is verified by Astra and is not professional accreditation.
Can I cancel, and are the courses taught in English?
Yes. All courses are taught in English, and you can cancel anytime. Stripe handles checkout, and your subscription works on phone and web.
