Aside from Hotforex, the only broker I know that offers Bitcoin trading is ICMarkets.
Here are the pros and cons that I can think of trading Bitcoin CFDs:
Pros:
- Easier to liquidate and withdraw cash since it's a contract with your broker
- Good for short term hedging if you hold Bitcoins, but see short term downside risks
Cons:
- Higher spreads since the broker does take on exposure too so they would need to be compensated accordingly
- May also have to pay spreads + commissions
