One year or five years in this forum makes no difference if that someone have not build a trust reputation. The member you trusted only had six posts in a year and is only a newbie account.
When I joined the forum in 2015, people were learning this fact the hard way. Here we are in 2022 and people are still learning the hard way. How much you want to bet this is never going to change?
I always assumed bitcoin attracted people who wanted a trustless form of money, but what I'm seeing is that a lot of people end up trusting complete internet unknowns, often with large sums of money. I've even fallen prey to scammers because of this, so I'm not casting aspersions on anyone--it's human nature to want to trust other people, but in crypto you really shouldn't. If you're doing deals on bitcointalk or anywhere else with someone you don't know, follow the advice given here and in so many other threads: use an escrow!!
$450 is a hefty amount for me
To some people, that's life-changing money. And even though it wouldn't even buy a decent bicycle where I live, it'd still piss me off to no end if I got taken for that much. Fuck these scammers.
