I fell victim to a cryptocurrency scheme on a platform called Wanabit.com. I sent cryptos to the platform, but now they have blocked my funds, making it impossible for me to withdraw or access them. Instead, they continue to ask for additional payments under false pretenses. At this point, I have nearly $18,000—my entire life savings—stuck on this platform.I have been trying to withdraw my invested funds to my other wallet, but they won’t release them. They say I need to deposit 50% of the amount to unlock it, and I can’t get in touch with support. The only communication available is through a chat that barely responds to me.I really need professional help
