#withdrawal-issue

Crypto 'trading platform' reversed my withdrawal, now demanding 3k balance for cash out. Is this another scam?

Hey everyone, i'm so utterly gutted right now. i met this guy, 'Alex', on tinder about two months ago. we hit it off, talked every day, really felt like we connected. he eventually introduced me to a 'crypto trading platform' where he said he was making decent money. he swore it was legitimate, even sent screenshots of his 'profits' and how easy it was to withdraw. so i put in a bit of money, then a bit more, eventually about SGD 8,000. i saw the balance grow (on *their* platform, of course). when i finally tried to withdraw about half of it last week, the transaction just... reversed. no explanation. then their 'customer service' tells me i need a minimum balance of $3,000 USD to even process *any* withdrawal, saying it's a new policy due to 'high volume'. this just smells like another layer of scam, doesn't it? i feel so stupid. what should i do? should i try to pay the 3k just to get my original money out? or is that just throwing good money after bad? i'm in singapore, how do i even report this properly? any advice appreciated, please be kind.
