I'm planning to buy a Scanmatik 3 for a small garage to perform diagnostics, coding and occasional ECU flashing on European and Japanese cars. Does Scanmatik 3 reliably cover VW/Audi, BMW, Mercedes, Toyota, Honda and Nissan? How often are software updates released, are there license or activation limits, and is the basic kit enough or should I purchase extra adapters/modules for bench work? Also curious about reliability in daily use.

I’m looking into opening a crypto savings wallet that promises high annual yields, like 10–14% on stablecoins and 6–8% on BTC/ETH. The idea of passive income sounds appealing, but I’m cautious: how are such yields actually generated, are withdrawals smooth in practice, and what kind of risks (custodial, liquidity, lockups) should I be aware of before committing funds? Would appreciate real experiences or warnings.
