Reading Pen Farming｜From a QR code on a piece of paper, my imagination of the "consumption behavior" of cryptocurrency

Every week I choose one day to walk from home to a coffee shop two blocks away to read and write.

On the bar, there are two small standing signs made of acrylic: LINE PAY and Jiekou Payment, which are privately called Taiwan's "Dianzhi Shuangxiong" (Dianzhi is the abbreviation of "electronic payment"), it should not be an exaggeration Bar!

For a long time, I have had an idea in my heart, and I dare not say that it will replace it, but if there is an additional sign next to it, which is a QR code specially created for cryptocurrency payment , how good would it be?

I try to figure this out from the standpoint of the store vs the consumer, and list three discussion directions:

1. What is the currency?
   Usually, the store owner does not want the price of a cup of coffee (or other products) to be "changed by day and night", so that it is convenient to lock in the profit of each cup. Following this line of thinking, it seems that it is safer to use " stable currency " to set the price?
   
2. The amount of gas fee <br class="smart">Continue to the above, take the most widely used USDT as an example, it should be no problem to buy high-priced goods, but if you add a cup of coffee, you need to add another dollar. From the perspective of consumers, will the “handling fee” (transmission through TRC-20 ) be prohibitive?
   
   One possible solution is to use a (blockchain) network with a lower "handling fee" to transfer money, such as LikeCoin chain, but it goes back to the first point of concern, which is the issue of currency price volatility.
   
   The second possible solution is an encrypted currency charge card, but it seems more romantic to scan the code and send it directly (to the other party's wallet)? And also involved in the third point to be discussed next.
   
   
3. I'm not an expert in accounting and taxation <br class="smart">in this area, but I vaguely feel that starting with a store that is exempt from issuing unified invoices will make things simpler; many of these stores offer "non-cash" transactions when , the first choice is mobile payment. If a credit card is further involved, it seems that an invoice will be issued.

My imagination of the " consumption behavior " of cryptocurrency is to hope that it will gradually become more popular.

In the beginning it was only an underground economic activity, such as the former #Bitcoin Pizza Day , now the #mattmarketbazaar ... In the future, maybe from sporadic to organized (an aggregator came out), from online to offline, from wallet To "wallets", from small businesses to large shopping centers, from private to official...

what! Which of the above links, you say, has the greatest resistance?

Perhaps the most difficult thing is nothing else. It's in front of you. It 's from closed resistance to open acceptance . It's your heart and mine.
