It seems there might be a slight misunderstanding in your question. While "Sher" could potentially be part of a name for a trading platform or a less well-known cryptocurrency, it is not widely recognized as a major cryptocurrency or a standalone exchange.

Here's what the search results indicate:

* Sherlock Wallet (SHER): There is a cryptocurrency with the ticker symbol "SHER," known as Sherlock Wallet. However, it appears to have very limited trading activity and a negligible price. Major exchanges like Coinbase and Binance indicate that it is not tradable on their platforms.

* Sherweb: This is a cloud solutions provider and does not appear to be related to cryptocurrency or stock trading.

* Share.Market & Mirae Asset Sharekhan: These are established platforms for trading stocks, IPOs, mutual funds, and other investment instruments, primarily in the Indian market. They do not appear to be directly associated with a cryptocurrency named "Sher."

* OXShare & Sheer Markets: These are brokers that offer trading in various financial instruments, including Forex, CFDs, stocks, commodities, and some cryptocurrencies. However, they don't seem to have a specific "Sher" coin or exchange.

* Gofaizen & Sherle: This is a legal consultancy firm that assists with obtaining crypto licenses in the UAE.

* Sher Legal: This is a law firm offering various legal services, including consultation on crypto assets.

In conclusion, based on the available information, there isn't a prominent cryptocurrency or exchange simply known as "Sher" that is actively traded.
