December 2021-January 2022 I was led into this trading platform, http://coindealrx.com/#/ where I transferred Bitcoin for the intent of investing. I had been skeptical at first and only deposited a small amount into the platform, in which I gained a good amount of interest and I was able to withdraw it. This trickery brought my guard down, so I decided to invest more but have not been able to withdraw any of it. The platform is withholding my funds and will not let me withdraw any cash out. They demand I pay a 15% security deposit, then I will be able access to my funds to withdraw. Tried to search the website, but it seems to have been wiped from the web.
