Taxes
How to declare Bitcoin to Spanish Hacienda 2026 step by step
Bitcoin capital gains are taxed in the IRPF savings base at 19% to 28% depending on the amount. They are declared in Modelo 100 (annual return), boxes 1626-1636. Balances on non-resident exchanges must also be reported in Modelo 721 if they exceeded €50,000 on December 31.
Modelo 721 explained: who must file, deadlines and fines
Any Spanish tax resident who held more than €50,000 in crypto on non-Spanish exchanges on December 31 must file Modelo 721. The window is January 1 to March 31 of the following year. Missing the deadline triggers a €300 minimum fine.
How much tax do you pay if you sell 1 Bitcoin today in Spain
In Spain, Bitcoin capital gains are taxed at 19% (up to €6,000), 21% (€6,000-50,000), 23% (€50,000-200,000), 27% (€200,000-300,000) and 28% (above €300,000). If you bought 1 BTC at €30,000 and sell at €90,000, the €60,000 gain generates roughly €12,900 in tax.
Wallets & security
How to recover a lost wallet: seed phrase, hardware and real options
If you kept the seed phrase (12 or 24 words), you can restore any compatible wallet (Ledger, Trezor, MetaMask, Trust Wallet) by importing it into a new device. Without the seed phrase, technical recovery is impossible except for specific KYC-verified custodial wallet cases.
Best cold wallets 2026: Ledger vs Trezor vs SafePal vs BitBox
Ledger Nano S Plus (€79) is the best value for beginners. Trezor Safe 5 (€169) offers the highest code openness and a touchscreen. BitBox02 (€149) leads in audited security. SafePal S1 (€49) is a solid budget air-gapped choice.
DCA & periodic investing
Yield & lending
Safe yield farming: how to evaluate a DeFi protocol before depositing
A yield farming protocol is reasonably safe if it meets: (1) TVL > $100M stable for 12+ months, (2) at least 2 audits by top firms (Trail of Bits, OpenZeppelin, Certik, ChainSecurity), (3) verified contracts on Etherscan, (4) publicly identified team, (5) sustainable APY <15% on stables or <30% on ETH/BTC.
Bitcoin-collateralised loans: complete guide to risks and options
You can borrow euros/USDC using Bitcoin as collateral at typical 30-50% LTV. Current platforms include Aave (DeFi), Ledn (CeFi), Nexo and Sygnum (crypto banking). Interest 6-12% per year. Main risk: forced liquidation if collateral price falls and LTV crosses the threshold.
Portfolio strategy
Crypto portfolio rebalancing: when and how to do it correctly
Rebalance your crypto portfolio when any asset deviates more than 10-15 percentage points from its target allocation, or at least once every 6 months if no deviation occurs. Common allocation is 60% Bitcoin, 25% Ethereum, 15% altcoins/satellites, adjusted for your risk profile.
The 60/30/10 strategy: how to allocate your crypto portfolio in 2026
60% in Bitcoin (monetary base), 30% in Ethereum + top 5 L1s (Solana, Cardano, Avalanche), 10% in high-conviction satellites (memecoins, AI, DeFi). This split maximises risk-adjusted return over 3-5 year horizons in historical backtests.
