Kraken Exchange
Kraken is the security-first exchange people mean when they say “I actually trust leaving size here.” Online since 2011, never lost customer funds to a classic exchange hack, early on proof-of-reserves, and properly regulated in places that matter (U.S., UK, EU rails). Fees aren’t Binance-cheap on day one instant buys are expensive, Pro is the real venue but versus Coinbase it’s often the sharper regulated pick. Spot, staking, margin/futures where allowed, and a growing TradFi crossover for eligible users.
