What makes you think a Bitcoin site might be a scam?

Before sending BTC to a website, what usually makes you stop?

For me, if the site looks new, the domain name looks weird, or the support page feels fake, I would probably close it. Same if they push me to pay too quickly.

Do you check the domain name before using a crypto site, or do you only care about reviews and reputation?

I tend to focus more on things that are encompassing and more effective than domain name check, in this order:

* Operated long enough without any reasonable/legitimate negative review on trustworthy review sites.

* No reasonable/legitimate serious review or complaints against them

* Search results about them on the internet need to be organic and more positive than negative.

*They address negative reviews against them in satisfactory manner

* They are recommended by trustworthy people or sites.

*They are licensed or sufficiently regulated by effective guarantor such as a country, forum, individual etc

* If not centralized/custodial, their opensource community has to be fairly active without serious issues

Bitcoin has a mining algorithm that was never designed to advance science, so Bitcoin tends to attract suckers which in-turn attracts scammers.
