I think it might be human nature, when people hear discounts everywhere they buy things that are not necessary ... and should when BTC drops or hears bad news don't easily panic and be provoked
No, it's not, it is just that most shopaholic if saw a discounted price would rather buy everything that they don't want just because they saw the discounted price. If you are really a risk taker then you wouldn't be spending money on the things that you won't need but rather invest it to actually gain a profit. And that's how businessmen do.
