What is the advantage of exchange carried out with the help of money, compared with a barter economy. Is the existence of a barter economy possible in modern conditions?

Money is preferable to barter when there is a high level of trust in the economy, i.e. their purchasing power does not fall rapidly (inflation), they can be exchanged for foreign currency. If hyperinflation has begun in the country, when prices are redrawn every day, hourly and almost every minute, then they try to get rid of money by purchasing as many goods as possible, which further spurs inflation. Ultimately, economic entities begin to settle among themselves not in money, but in barter as a more stable money equivalent in value terms. Barter thrives when hyperinflation thrives.

The main disadvantage of barter is that I must have what you need, and you must have what I need. If there is no such match, then barter is impossible.

Money can be easily exchanged for a product or service without intermediaries; it is the universal equivalent of value when its price is stable over time.
