If you sent crypto to the wrong network, forgot a memo, or pasted the wrong address, you are not the first. Whether you can get the money back depends on where the coins actually landed and who controls the keys to that address. This guide explains which mistakes can usually be fixed, what to do in the first hour, and how to avoid it next time. Why one token can travel on several networks A stablecoin like USDT or USDC is not one single thing on one single blockchain. The same token exists in different versions on different networks: Ethereum (ERC-20), TRON (TRC-20), BNB Smart Chain (BEP-20), and layer-2 networks such as Arbitrum or Base. These networks do not talk to each other automatically. If you withdraw USDT on BNB Smart Chain but the receiver only watches Ethereum, the coins sit on BNB Smart Chain and the Ethereum side never "sees" them. Kra...

Photo: Karsten Ratzke / Wikimedia Commons , CC0 Crypto inheritance in Germany is a topic most Bitcoin owners avoid until it is too late. Legally, your coins pass to your heirs like any other asset. The practical side is the problem. If nobody knows which exchange you used, or where your hardware wallet and recovery phrase are, your family may never reach the money at all. This beginner guide explains how heirs claim crypto, how it is taxed in Germany, and what you can prepare today. Is crypto part of your estate in Germany? Yes. Under German law, everything you own passes to your heirs as a whole when you die (universal succession, § 1922 BGB). That includes Bitcoin and other crypto-assets, whether they sit on an exchange or in your own wallet. Germany's highest civil court, the Bundesgerichtshof (BGH), confirmed in a landmark ruling on 12 July 2018 (III ZR 183/17) that a user contract for an online account generally passes to the heirs by universal succession, and that heirs...

In the EU, the honest answer is: it depends on who holds your coins, how, and whether the firm is licensed under MiCA. Your bitcoin is not covered by the €100,000 bank deposit guarantee. But since MiCA, a licensed exchange must keep client crypto legally and operationally separate from its own assets, so creditors cannot simply take it. Below: what the rules require, what they don't promise, how euro balances are treated, and a practical checklist. Why "not your keys" still matters When you buy bitcoin on an exchange, you usually do not hold the private keys; the exchange holds the coins for you. If the company fails, the key question is whether your balance is your property held for you, or just a claim against a bankrupt company. BaFin puts it plainly: crypto is not covered by deposit insurance, and investor compensation normally does not appl...

Photo: FlippyFlink / Wikimedia Commons, CC0 Buying Bitcoin on an exchange is easy. Taking it off the exchange is the step many beginners put off, because one wrong character in an address feels scary. This guide shows how to move Bitcoin from an exchange to a hardware wallet safely, step by step, with the extra checks European exchanges now ask for. The process is the same whether you use a Trezor, Ledger, BitBox or another device: get a receive address from your wallet, verify it on the device screen, whitelist it on the exchange, send a small test, then send the rest. Why move Bitcoin from an exchange to a hardware wallet? Coins on an exchange are held by the exchange. You see a balance, but the company controls the keys. A hardware wallet keeps the private keys on a small device you own, so only you can sign a payment. Many long-term holders keep a small trading balance on the exchange and move the rest into self-custody. Self-custody also means self-responsibility. If you lo...

Photo: FlippyFlink / Wikimedia Commons, CC BY-SA 4.0 You click "withdraw" on your exchange, paste your wallet address, and instead of a confirmation you get questions: Who is the recipient? Is this your own wallet? Can you sign a message to prove it? If this has happened to you, nothing is wrong with your account. It is the EU "Travel Rule" at work. This guide explains what the rule is, what changes when you move coins to or from your own wallet, and how to get through the checks calmly. What is the EU Travel Rule? The Travel Rule is the common name for Regulation (EU) 2023/1113 on information accompanying transfers of funds and certain crypto-assets, also called the Transfer of Funds Regulation. It was published on 9 June 2023 and has applied since 30 December 2024 , the same day the MiCA rules for crypto service providers started. Banks have long had to send payer and payee details with a wire transfer. The regulation extends this to crypto-asset servi...
