Any company that does its accounting in bitcoin is obviously inpcompetent at managing its money. We leave it as an exercise to compute the probability that it will deliver what it promises to its clients. Extra credit for figuring out how many months it will take to go bankrupt.
1/The statement about the bitcoin accounting is obviously not true. It just depends whether it is your income or your expenses that are accounted in BTC. For example, all bitcoin pools and miners have their incomes accounted in BTC and some of them are still not bankrupt.
2/ Czech companies usually pay their expenses in Czech Koruna, not Euros.
Sorry about the currency mistake. (Inexcusable, since I still have some Czech banknotes somewhere here in my office, mementos of a conference in Plzeň some years ago...)
But the accounting part is very serious.
The ~1% yearly inflation of dollars and euros is already a complication for accounting; but if it is ignored it the errors are of that magnitude, and therefore are not likely to affect the company's financial planning -- e.g. how much to charge for the product in order to make a profit of about 10%.
The month-to-month variation in the value of BTC, on the other hand, is MUCH too large to ignore. You cannot do a budget in BTC, to plan for a 10% profit, if the unit of accounting may be worth 100$ when your client prepays, 1200$ when you close a deal with a supplier, 800$ when you pay him, 400$ when you ship the unit, and 600$ when the client returns it for refund.
Budgeting in BTC is MUCH worse than a building contractor using "strides", "spans", "arm lengths", and "car widths" in his engineering plans. Much wose even than trying to build an airplane with a measuring tape made of latex. (Can latex can stretch to 12 times its rest length?)
