"Dynamic pricing" poses a dangerous future for the unprepared. Businesses can now adjust prices in real time, for individuals, depending on data they easily gather. They ALLREADY do it with airline tickets. IT is getting where even groceries or Amazon purchases will be priced that way. Insurance companies have used it for years based on zip code. Wall Street brokers have used it in trading to cheat the retail investors.
THERE is only one technology that can get around, or offer a defense against, this dynamic pricing. And, there is only one real money based on that technology, BITCOIN. Bitcoin is partly based on Public and private key encryption. This public/private technology allows some important identifying information to be masked. The identifying information can be masked in a variety of ways with Bitcoin, crypto technology, and blockchain platforms, decentralized servers, and the good old VPN networks. When it come right down to it, Bitcoin is the safest money for privacy ever invented. And, privacy is a main defense against dynamic pricing.
