Octa, formerly OctaFX, is a forex and CFD broker popular across Asia, the Middle East and Africa. It holds a CySEC licence in Europe, but its bonus-taking clients are served by an offshore entity in the Comoros, which is a meaningful trust consideration. Its deposit bonus is margin credit that becomes withdrawable only after heavy lot volume.
Risk warning: Trading carries a high risk of losing money, especially with leveraged products such as CFDs. A bonus does not reduce that risk. Only deposit what you can afford to lose.

Octa adds 50% of every deposit as a bonus you can use as margin. The bonus itself becomes withdrawable only after you trade a volume of lots tied to its size.
