This one has both demo account, and the min deposit for the real account also starts from something like $2 (in btc or ltc) and no KYC verification is needed. Here's the link.

Fees are important, their trading platform is important, and of course, reliability is important. After going through a bunch of different options myself, I decided to stay with Evolve. Here's what they offer:

Pros
Easy account creation
No Identity verification needed
Deposits with Bitcoin and Litecoin
Demo account
US Customers welcome
Mt4/Mt5/Web trader/Phone apps

Cons
Not Regulated
Only accepts BTC and LTC payments, no fiat

Here's a longer Evolve markets review.

From my experience, Windscribe is the best - free version offers 10gb/month, plus you can get 5gb extra for tweeting about them.

You could try Evolve - it's an anonymous crypto/forex broker, and all you need to register is an email account. And while I'm sure it's lacking some kind of legal protection, withdrawal takes a few hours and has so far been reliable. And the min deposit is nothing, so it's easy to try it out. You can trade both cryptos and forex, and they support mtf4, mt5, and their own web trader is available as well. Here's also an Evolve review for you.

Laptop is generally good enough, but if you have the space, a desktop machine with multiple screens is definitely better.

Trading might be the safest (cryptos, forex), assuming you're willing to learn a bit, and ready to stick to your stop-loss limits which you hopefully set each and every time. I.e. brokers like this one allow you to trade without authenticating yourself (so it's anonymous) by just requiring your email for signing up/deposit/withdraw - and obviously, you can deposit with bitcoin or litecoin.

Gambling on the other hand is...well, gambling, so unless you get lucky, there's nothing else working in your favor.

This seems to be a rather old thread, but if someone is till looking for something like this, then instead of an exchange, why not go for an anonymous forex broker which accepts Bitcoin and litecoin deposits.

So far I've mainly using Evolve (https://www.eifu.org/Trading/article_983_What-is-the-best-anonymous-forex-and-crypto-trading-platform.html), and last time I tried to withdraw, it worked well as well, took a few hours. They offer bitcoin and litecoin deposit options and they only ask for your email to register and start trading.
