Can the stock price go up even if no one is buying?

Let's assume there's this random company (XYZ)--that few are aware of--is selling stocks and they're doing really well. If their stock price is at $50 and no one is buying, will it still go up? Do stock prices only go up when people are buying?

Credit card numbers on the back - is it not less secure?

I got a new credit card today (replacing the old one which was worn out) and I noticed something new - all the numbers have now moved to the back of the card, leaving the front empty. Apparently it's been trending for a while now, and I do agree…

Why do some online stores not ask for the 3-digit code on the back of my credit card?

How is it that some e-commerce stores are able to process credit card transactions without getting the 3 (or 4-) -digit security code from the back of my credit card? What value does this code add if it's optional in the end?

Is it really risky to make your IBAN public?

It seems that people are reluctant to give their IBAN to strangers. I saw someone downvoting an app only because it shows the IBAN in clear on the main screen. Is this rational? What could someone do knowing your IBAN?

Is it safer to send credit card number via unsecured website form or by e-mail? What safer options are there?

I want to buy something from a VERY REPUTABLE Asian seller. They've got a lot of good references all over the internet. The only thing is, they are quite old-fashioned and so is their website. They want you to send your order via UNSECURED FORM on…

When I obtain a new credit card, I take care to remember the three-digit CVV number stamped into the back of the card, and then remove the number from the card (very thoroughly, because it's usually stamped very hard into the card). This is so that…
