Thanks for taking the time to put together this list. Another one that offers crypto is ICMarkets, and they've been reasonable in terms of pricing so far. They're also true ECN, which means they compile their prices from their liquidity providers to give the retailer the best one, instead of most brokers who are market makers and take on losing trades for their own gain.

Another consideration is ease of withdrawal. Some brokers make it near impossible for you to cash out once making a profit. That's hard to know for sure so its something you've gotta test in small amounts before committing.
