There is a pattern in all these scams.
1. Beautiful women
2. Apposite rich lifestyle
3. Love bombing
4. Endless promises for future life together
5. End goal : invest to become rich
They probably try with 100s of innocent souls , toy with the emotions and then get some to successfully invest.
They play bait for sometime until the poor guy is lured to invest more, whilst in reality that money is actually going into their pockets.
Bastards ! the bloody lot of them !
Anything that traces back to any *island* , be it anywhere (ofshore). Is a definite scam. Because islands like Seychelles , cayman islands, st Vincent and Grenadine, and the rest of the lot are a host place for organized criminal activity like these. As they are well known tax heavens.
Probably need some good hackers to track these chums and hack inside their interfaces.
And don't go for so called *recovery companies* , I believe they are connected with these same organizations.
Best recourse may be through chargeback, if you sent the money to buy the crypto from your bank account.
