Our take
bitstack
Bitstack delivers an intuitive mobile gateway designed specifically for everyday European savers who wish to build a Bitcoin position without actively tracking markets or executing manual spot orders. By connecting existing bank accounts through open banking APIs, the application calculates spare change from routine card spending, automatically accumulating satoshis on a recurring schedule. In addition to round-up mechanics, the platform supports single purchases, automated recurring dollar-cost averaging plans, and a dedicated debit card product that directs cashback rewards into Bitcoin balances.
While this streamlined workflow makes accumulation frictionless, it trades off fee efficiency against extreme simplicity. Standard retail buying fees sit noticeably higher than dedicated spot exchange order books, making Bitstack less suitable for active traders or high-frequency capital deployment. However, for casual savers seeking a compliant, regulated European application with clear on-chain withdrawal pathways, Bitstack presents a functional, approachable entry point into digital asset savings.
Divly
Divly delivers a focused cryptocurrency tax calculation engine designed to eliminate the friction of regional tax compliance across European jurisdictions. Headquartered in Sweden and operating since 2021, the service distinguishes itself by supporting specific domestic tax reporting formats, such as Sweden Skatteverket K4 forms, alongside localized outputs for Norway, Finland, Denmark, Germany, and the United Kingdom. Instead of relying purely on generic capital gains summaries, the platform maps taxable dispositions, mining rewards, staking yields, and gifts to precise regional tax code definitions.
The system operates on an entirely non-custodial basis, using read-only API keys and standard spreadsheet imports to reconstruct portfolio histories. While active traders with hundreds of thousands of decentralized finance trades may hit tier constraints or need manual mapping adjustments, Divly provides a streamlined workflow for Nordic and European investors seeking compliant, localized annual filings.
