Sales are everywhere. Sale on shoes, bags, shirts, gadgets and everything. Malls and shops use this technique to attract buyers, but you know what? Do you think you've been discounted a higher price than ordinary? No. Instead of saving 20%, you spend 80% on things you dont really need. This is not economical and most of us are easily lured to it. This is what i hate about people. When there's useless trending items on sale, they buy immediately even on credit cards but if bitcoin drops, they talk negative about it. Normal mindset wants to get temporary attention. Not permanent comfort.
Sales on items and bitcoin is really different. Bitcoin is a digital currency that can be used to buy things or trade to earn profit. While items that go on sale are consumed by people.
There are two people that talks negative about bitcoin. One to spread fud so they will benefit from it. And the other one who don't know how it functions at all and the potential of blockchain tech.
I don't see anything wrong about sales. It's just people decision if they will spend compulsively during those season. If you have extra budget and a wise spender, you can buy more items during sale than a regular price.
