Elroy Ryon, full name Elroy Ryon Heisterkamp, is a Dutch crypto trader, mentor and content creator who operates under the brand Het Crypto Huis ("The Crypto House") from Hoorn, North Holland. His core community asset is the Day Trading Community (DTC), a knowledge-sharing platform for Dutch and Belgian day traders and investors that acts as the connective tissue between his YouTube channel and his paid Elliott Wave course. His output includes the "Het Laatste Crypto Nieuws" video series, Elliott Wave educational content and explainer videos on topics such as copy-trading mechanics and exchange selection, distributed across YouTube, a real-name LinkedIn, a clean Instagram (@elroyryon) and a Linktree that consolidates the rest of his stack.

His story is one of resilience: he started trading in 2014, blew up his account, came back and built Het Crypto Huis from scratch into a two-time award-winning trading brand, with appearances in Dutch mainstream media including RTL4, De Telegraaf, AD and Business Insider. He is also, unusually for the space, a crypto fighter: he stepped into the ring at Crypto Fight Night in Singapore, dominating the early rounds before a dislocated shoulder ended the bout. It is the same blood, sweat and discipline arc he brings to his trading persona.
