Kraken vs Bitstamp — 手續費與條件比較

Kraken — Tier 1 (30-day volume $0+), Kraken Pro cross-platform fee tiers. Instant Buy pricing excluded. Kraken has no platform token. futures_max_leverage = 50x per the Kraken Perps support article (product page also states 'up to 50x'; region-dependent). insurance_fund=false: Kraken Futures uses a Position Assignment System with liquidity providers instead of a dedicated insurance fund. Crypto withdrawal fees (support article table, 2026-09-23): BTC 0.000015 BTC on the Bitcoin network (Lightning 0); USDT 1.00 USDT on Tron/TRC20 (cheapest: TON/Plasma/Tempo 0.10, Ink 0; Ethereum 0.7935). HQ left null: Kraken states it was founded in San Francisco but publishes no headquarters; listed_coins left null because no official total is published (Assets API returns 843 entries incl. staking variants and tokenized equities). listed_coins = 627 from kraken.com/buy ("buy over 627 cryptocurrencies"); the homepage advertises "600+ crypto pairs".

Bitstamp — Unified Fee Schedule valid from 1 September 2026, lowest tier (30-day volume < $10,000), standard pairs. FX/stablecoin pairs are cheaper (0.06%/0.08%). Derivatives are offered by a separate entity (Bitstamp Financial Services, Slovenia) and are not included here — treated as spot-only. insurance_fund = "market-leading crime insurance" on custodied assets per official blog, not a SAFU-style fund. Users = "over 4.5 million customers" (official blog). listed_coins = 80 from the official blog wording "80+ cryptocurrencies" (global; US site advertises 35+). kyc_required = true per the official blog ("each account has to be verified before it is allowed to trade"). Customer-support page promises 24/7 live support by phone and in-app message but does not name a chat widget, so live_chat_support stays null. Crypto withdrawal fees: the official Fee Schedule (checked 2026-09-23) states a variable fee "disclosed before you confirm the withdrawal" and publishes no figure, and the public currencies API carries no fee field — BTC/USDT withdrawal fees stay undisclosed. Re-verified 2026-10-19 by weekly review in-browser: Unified Fee Schedule "Valid from 15 October 2026", "< $10,000" Standard 0.30% maker / 0.40% taker; the upcoming schedule valid from 21 October 2026 keeps the same Standard tier (adds RLUSD to the USDT stablecoin column). Unchanged.
