Understand securities, digital assets and retail investing before you commit a single euro.
JT Technologies GmbH is a research and education desk covering online brokerage mechanics, securities trading, cryptocurrency markets and retail investing. Every page here is written to inform, not to sell.
Three ledgers, one plain-language desk
We organise our material the way a brokerage back-office organises accounts: by instrument type. Pick the ledger that matches what you're trying to understand.
Securities trading
How order books, exchanges, settlement and clearing actually work behind a standard buy or sell ticket.
Cryptocurrency markets
Custody models, on-chain settlement, exchange structure and the risks specific to digital assets.
Retail investing
Fees, diversification, time horizon and the questions worth asking before opening any account.
Most losses start with a misunderstood mechanism, not a bad market call.
Slippage, margin calls, custody risk and withdrawal terms rarely appear in marketing material. We write the explainer we wish existed before we opened our first account.
- Independent explanations, no sponsored placements.
- Written for beginners, reviewed by people with markets experience.
- Updated as market structure and regulation change.
Not investment advice. Nothing on JT Technologies GmbH constitutes a recommendation to buy, sell or hold any security or digital asset. We do not open accounts, hold funds, or execute trades on behalf of anyone.
