What type of scam did I just fell for? Help pls

Hello – I am not sure if I am able to post token addresses here – but our close knit TG group had a respectable member post a token called '$GSNAI' – or gensyn. It's a arb > panscake swap token. You can find this on DexScreener but I do not want to post the CA incase this post gets hidden.

Basically none of us can sell. We are all 5x up – one of our members said he couldnt sell so I did a 20$ test transaction on pancake swap – it went through. I let it go and it went right up in price – I was ready to cash out. My $200 eth is now $950 eth according to pancake swap. However – whenever I go to trade it – it says some error occured. No reason behind it – exact same way I did my test trade for $20.

We knew the token looked suspicous but a few of us aped at it as usually these coins wouldnt get called in this group – especially from this member.

What kind of scam is this – I understand I may never see my initials – let alone more $900+ if it was a legitimate trade – so I assume theres no way around this?

I just need to learn what this token his – how we are able to buy it but NOT sell it – yet once time I did a $20 test sale and it went through?

Twice also with pancake swap – it said the full amount went through successfully – but I got nothing in my wallet.

I also see all these weird transactions in my history…

Here is a txn cash for one of the 2-3 times it said it was succesfull: https://arbiscan.io/tx/0x6941ba87befc9208637304b14f0c525722fe16bd358f9a8747e7bb2661eace48

This is also my wallet with all my history: https://arbiscan.io/address/0xfd334922cea3c5bdc1ac2709e1c19d673429e223

Can someone please let me know what kind of scam this is – what to look out for next time – how I managed to trade $20 with a test but now it won't – and is this money 100% gone forever and bad luck ( which I accept fully)

Same error I always got – occasionally like mentioned earlier the swap was succesfull but nothing came through at all.

Some education about this f' up would be greatly appreciated – thanks in advance.
