The arrival of XRP at a price of $1000 is theoretically very likely, but practically unrealistic at this time for several economic and technical reasons, including:
1. Market Cap
Currently, there are about 55 billion XRP in circulation.
If the price reaches $1000, the market cap would be: > 55 billion × 1000 = 55 trillion dollars.
This number is higher than the Gross Domestic Product of the United States and is larger than the total market cap of all cryptocurrency markets combined by hundreds of times.
