Low Fees
eToro is great for traders seeking zero-commission stock and ETF trades, an efficient platform, and access to copy trading. That said, there are hidden fees, education is sub-par, and eToro doesn’t offer the same range of investments as traditional brokers. eToro’s crypto offering includes 16 different coins. Although crypto fees are cheap, you can only withdraw your crypto assets with a dedicated eToro wallet.

Kraken was founded in July of 2011 and offers trading on 18 different cryptocurrencies, including Monero (XMR), Ripple (XRP), and Dash (DSH). Kraken currently offers a web platform but does not have a mobile app.
Offers Gemini Dollar
Founded in 2015 by the Winklevoss twins, Gemini is a licensed digital asset exchange and custodian built for both individuals and institutions. Gemini lets users buy, store, and sell Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Bitcoin Cash (BCH), and ZCash (ZEC), as well as the self-named Gemini dollar (GUSD).
Best Mobile App
Robinhood Crypto allows users to trade Bitcoin (BTC), Ethereum (ETH), Bitcoin Cash (BCH), Litecoin (LTC), Dogecoin (DOGE), Ethereum Classic (ETC), and Bitcoin SV (BSV). Ten additional coins can be added to a watch list. Robinhood Crypto is best-fitted for users who trade multiple classes of assets.
