What is an alpha player?

Could you please explain to me what exactly is an alpha player in the world of cryptocurrency and finance? I've heard this term being used quite frequently, but I'm still unclear on its specific meaning and significance. Is it someone who consistently outperforms the market, or perhaps a skilled trader with a proven track record of success? I'm eager to gain a deeper understanding of this concept and how it applies to the dynamic and fast-paced world of digital currencies and investments.
