I'd go with liar.

I feel like a scammer when I trade worthless fiat for goods/services I want.

I feel like a scammer when I provide value to Bitcoiners & they pay me in sats.

I'm always honest about it & will admit to being a scammer if challenged. I will tolerate & trust scammers but I can't trust a liar.

The worst kind of liar is one that lies to themself.
