It is highly unlikely that Shiba Inu (SHIB) will reach $1 per coin. Here's why:
There are currently over 549 trillion SHIB in circulation, according to CoinMarketCap. https://coinmarketcap.com/currencies/shiba-inu/ If each SHIB were worth $1, the total market capitalization of Shiba Inu would be more than all the money in the world. This is not a feasible scenario.
The price of a single SHIB would need to increase by thousands of times to reach $1. This kind of dramatic price increase is highly unlikely for any established cryptocurrency, let alone one with such a large circulating supply.
