Would you buy a product from an online shop that shows no address, country, or employees?

Several pools are not legal entities so they have no laws they are required to follow or taxes to pay, and obviously you can't chase them if they rug.

Do your due diligence, and if something looks suspicious it usually is. I think checking for an address is an obvious thing to do when choosing who do to business with but it seems like people lose all common sense when they get into crypto.
