Amazon recently opened its first "no checkout" store in Seattle, now followed by Sainsbury's opened similar "till-free" store in the UK. Such environment, where there is no cashier or even point of sale per se, is ideal for cryptocurrency payments. Till-free/no checkout stores are obviously unsuited for cash payments (or vice versa?), so the only option (besides crypto) is plastic card, or the card linked to your mobile phone app (i.e. Apple Pay). But what if you need some privacy and don't want to use plastic card? Maybe privacy is not that important for some people in grocery stores, but there will be other kinds of till-free stores... Or you simply don't have a bank account and plastic card, or your card is not accepted by Apple Pay? Here crypto goes on stage, because it combines the best features of two words: cash (it's anonymous and secure) and plastic cards (it's virtual and can be used on mobile phone).
How corporations want to put Bitcoin into centralized proprietary box so they could take control over majority of cryptocurrency transactions
Here is more details about Bakkt - a Microsoft/ICE/Starbucks plan to centralize Bitcoin (and I guess other cryptocurrencies in the future) trading.
Imagine that dozens of mutual funds, pension funds, and endowments hold Bitcoin in the Bakkt warehouse. If Asset Manager A buys $200 million in Bitcoin from Asset Manager B, the Bitcoin tokens simply move from B’s account at Bakkt to A’s account at Bakkt, via a trade on the ICE exchange. The total number of Bitcoins held at Bakkt doesn’t change. Let’s assume that millions of those transactions happen every day, all inside the Bakkt ecosystem. Bakkt simply keeps a ledger of those offsetting Bitcoin debit and credits. The individual purchases and sales don’t need to be broadcast to the blockchain.
Basically, Bakkt warehouse is going to be another centralized exchange with private version of Bitcoin Lightning, a singleton proprietary off-chain settlement machine where all fees associated with transactions are paid to the single owner of the warehouse. Such approach obviously contradicts the principle of cryptocurrency decentralization. Although unlike credit card payments system banks are not part of this scheme, corporations are still going to set the rules of the game. You will have to have an account in this system in order to pay or get paid, which means there is still someone who decides whether you are or you are not eligible (not to mention privacy and security concerns associated with any centralized system).
