A 300% deposit bonus immediately attracts attention, but the percentage alone tells you very little about the broker or the real value of the offer. In practice, a promotion this large usually requires a closer look at two possibilities: an unregulated broker using an aggressive headline to attract deposits, or a real promotional campaign with conditions that still need to be understood.
Why a 300% deposit bonus deserves extra scrutiny
A 300% bonus can make the account balance look much larger than the trader's deposit. That does not mean the bonus is cash, guaranteed profit or loss protection. Before registering, check who operates the account, whether the broker publishes verifiable terms and whether the bonus is available through a clearly identified entity.
The first warning sign: an unknown or unregulated broker
An unfamiliar brand is not automatically a scam, but a large bonus combined with no transparent company information, no verifiable entity and no clear withdrawal policy is a serious warning sign. Check the legal name, address, regulator information, client agreement, payment methods and independent evidence of an operating client base before depositing.
The second possibility: a real promotion with important limitations
A broker can run a genuine 300% promotion for a limited campaign instead of offering the same percentage permanently. Even when the offer is real, the bonus may be promotional credit used as extra margin rather than withdrawable funds or drawdown protection. Read the practical account rules, not only the headline percentage.
HankoX and Bullwaves: real promotions with important limitations
HankoX is a useful example of why percentage and trust should be assessed separately. It is known among active traders and can run higher deposit-bonus promotions, including 300% campaigns, but it is not publicly regulated in the same way as a broker with a recognised public regulatory register. Its proprietary app also provides account-analysis features, including AI-assisted analysis, while it does not use MT4 or MT5 as its trading apps. Bullwaves is another example where the bonus should be treated as extra margin rather than drawdown protection: if equity falls below zero or the deposited funds are exhausted, the account can be liquidated and the bonus removed. Read the broker terms and our reviews before evaluating either promotion.

Does a 300% bonus protect drawdown?
Usually, traders should not assume that it does. A bonus can increase the margin shown in the account while leaving the deposited balance as the real loss limit. If the loss reaches the deposited funds, the account may be liquidated and the bonus removed. This is different from a bonus structure that explicitly remains available through drawdown, such as the conditions described in our Ultima Markets research.
Checklist before accepting a 300% bonus
Verify the broker's legal entity and regulatory status.
Read the complete bonus terms, including volume, expiry and withdrawal rules.
Confirm whether bonus credit is margin only or can absorb drawdown.
Check spreads, swaps and low-commission or commission-free account conditions.
Assess the platform, execution, deposits and withdrawals independently of the promotion.

FAQ
Does a 300% deposit bonus mean the broker is a scam?
No. The percentage is a reason to investigate, not proof of fraud. Verify the entity, terms, reputation, withdrawals and account mechanics before making a decision.
Is HankoX regulated?
Do not assume that it can. The bonus may be promotional margin with separate volume, expiry and withdrawal conditions.
Can a 300% bonus be withdrawn?
HankoX is not publicly regulated in the same way as brokers listed on a recognised public regulatory register. Traders should weigh that limitation against the broker's reputation, platform, terms and their own risk tolerance.
