What nationality is Sharky?

Could you please clarify the identity of Sharky? Are they a person, a company, or an entity in the cryptocurrency and finance world? Without more context, it's difficult to determine their nationality. If Sharky is a public figure or well-known in the industry, I may be able to offer an educated guess based on their background and public information. However, if they are a pseudonym or operate anonymously, it may be impossible to accurately determine their nationality. Could you provide any additional details that might help me answer your question more accurately?
