When you receive a sign-up gift, you cannot withdraw it to your card immediately. I couldn't understand for a long time why the funds were "frozen" until I read an article about wagering on <a href="https://gmblwiki.com/">gmblwiki.com</a>;. It explains how many times you need to play through the amount to make it available for withdrawal. Now I always check this coefficient to realistically assess my chances of success. This significantly simplifies planning my gaming balance.
