CoinTracker Asked Me to Pay More Every Time Before Releasing My Own Money

CoinTracker asked me to pay €40,000 before they could transfer my money to my bank account. Was I scammed by them? I refused to pay, and now they’re threatening to block my account—they even showed me proof of it. I wanted to verify all the issues before making any payments. I’ve done this a few times before and was always asked to pay more. Whenever I became skeptical, they would block the account until I paid to “refresh” it. I’ve already paid a few thousand euros.
