I usually compare bonuses by looking at the real value rather than the headline percentage. For example, upgrader.pro promo codes can be assessed by checking whether the bonus applies to every deposit, who can use it, and whether there are restrictions on bonus funds. The HELLAGOOD code offers +5% on deposits, which could be useful before opening cases or joining upgrades. I’d still check the current terms directly on Upgrader.pro, since eligibility and bonus rules can matter more than the percentage itself.
