Brainstorming Random Thought Idea (Detoken)

I don't like making posts, but would like to brainstorm a shower thought;

​

I personally want to use BCH and have places accept BCH but this is not always possible as we know.

​

A middle answer to this exists in payment cards offered by some exchanges that transfers your crypto to fiat for each and every transaction and is accepted everywhere debit/credit cards are.

​

One of the problems this creates I believe, is that each one is a taxable event, and would require tracking and accounting.

​

So my question is, in theory, could a card be created in the interim until BCH is accepted as BCH, that does the following: (Storytime)

​

- Transaction for a cup of coffee ($1) on the 3rd March

- Detoken hedges $1 of BCH decentralized on the 3rd March for X amount of blocks

- Transaction for a sandwich ($4) on the 3rd March

- Detoken hedges $4 of BCH decentralized on the 3rd March for Y amount of blocks = (X amount of blocks - how many blocks have passed) (so they complete on the same block)

​

- Repeated for all spending for a period of estimated 1 month of blocks. All transactions then become unhedged at the end of the month. At that point the card removes the required amount of spending from your BCH wallet to cover the cost of all transactions in 1 transaction, and whether BCH goes up $1000 or down to $100 it wouldn't matter due to the fact you locked in the dollar amount of BCH at the point of transaction.

​

- End of the year would only need 12 taxable events for a year of spending on the card.

​

This would also then give a massive liquidity pool of BCH for people who wish to go long on leverage in a decentralized way.

​

As a seed of an idea, is this completely terrible? Try to be nice.
