Bitcoin has the advantages of being the natural shelling point (the first big cryptocurrency), having a proven (if suboptimal) improvement / decision making process (many smaller ccs have not made significant changes to their tech, and so one can't know how they would handle that), not having an overly powerful scripting language. Many weaknesses in tech can be fixed or built around. Adoption, community, and trust are hard to get.
