You evidently fail to understand that if a contract that transacts at some point in the future for X number of Bitcoins, THERE IS NO INSTANT CONVERSION. Now most companies hedge future currency risk but the cost of those hedges for a WILD, UNSTABLE thing like Bitcoin is very, very expensive, making it impractical to do business in.
1. cut back on the expresso - and capitalization.
2. there is almost instant conversion.
It sounds as if you have never had personal experience in making a transaction conversion with crypto?
Have you? Did you make your transaction using Paypal, Square?
And while you wouldn’t dream of accepting crypto, many kinds of businesses do exactly that.
You can shop online and even buy cars. We are in the early stages.
Bitcoin is the tip of the iceberg on crypto. It is just one crypto.
A quick google indicates that instant conversion happens, as my own experience would indicate:

Instant Conversion Capability
The most important of these innovations include the option of instant conversion at the time of purchase. Buyers are allowed to pay in Bitcoin by the merchants but the Bitcoin payment companies allow instant conversion to fiat as well, thus reducing the volatility aspect of the cryptocurrency. This is followed by many of the top crypto payment outlets including Bitcoin ATM cards and QR code-based payment services.
Businesses can also opt for an option that automatically converts crypto into fiat and deposits it directly into their accounts. So, if a person buys merchandise or services online with the help of Bitcoin, the seller may not have to be worry about any price fluctuation of Bitcoin as he is getting his required fiat amount directly into his/her account.
