If someone paying you too much for it, double be careful about it.
I bought twice for 2000 sats per semux and had no problem. I am now offering 1000 semux for it. I think it is a fair price with the current situation after btc airdrop price may get lower from this.
If you want a better deal I can find someone who pays 2 btc for 1 semux but you should send it first with no escrow
