Our take
BitMEX
BitMEX remains a foundational venue in the cryptocurrency derivatives sector, distinguished by its creation of the perpetual swap contract and its robust market engine. The platform provides professional derivative traders, quantitative desks, and active hedgers with exceptional order execution speed, advanced conditional order types, and detailed market depth across major digital assets.
While BitMEX has expanded into spot trading and passive yield products over recent years, its core identity is firmly anchored in leveraged derivatives. The venue offers competitive fee tiers, including maker rebates on select volumes, but operates under stringent international compliance controls that restrict users in key jurisdictions such as the United States and parts of Europe. For qualified international market participants needing sophisticated margin controls, BitMEX stands out as an established, battle tested derivatives marketplace with substantial institutional grade tooling.
Koinly
Koinly delivers a comprehensive tax calculation and portfolio management solution designed to handle messy crypto transaction histories. By connecting read-only API keys, public wallet addresses, and CSV records, the platform consolidates activity across centralized trading venues, self-custody addresses, and smart contract protocols. The core strength rests in its extensive regional compliance settings, which support country-specific accounting methods such as FIFO, LIFO, and share pooling rules in the United Kingdom or average cost basis in Canada.
While the service offers free transaction syncing and balance monitoring, downloading official tax filing forms requires an annual tax year license. Pricing scales by total transaction count, which can become costly for automated bot traders or active yield farmers. For individuals seeking clear tax liability calculations and downloadable reporting forms, Koinly provides an established and reliable operational setup.
