J\u2019ai d\u00e9couvert le Bitcoin en 2016, mais c\u2019est en 2018, en pleine phase baissi\u00e8re, que j\u2019ai r\u00e9ellement plong\u00e9 dans l\u2019analyse des cycles, des projets et des opportunit\u00e9s que propose l\u2019\u00e9cosyst\u00e8me crypto. Aujourd\u2019hui, je consacre mon temps \u00e0 l\u2019\u00e9tude des tendances du march\u00e9, \u00e0 la recherche de projets innovants, et au partage de strat\u00e9gies accessibles aussi bien aux d\u00e9butants qu\u2019aux investisseurs aguerris.

Que ce soit pour du swing trading, du scalping ou de l\u2019investissement long terme, je m\u2019efforce d\u2019apporter une vision structur\u00e9e et pragmatique.
