According to the dictionary, a cult is "a religion or sect considered to be false, unorthodox, or extremist, with members often living outside of conventional society under the direction of a charismatic leader."
The only difference between a relgion and a cult is how many followers it has. So, a cult can become a religion no matter how ridiculous it is as long as it has enough followers. Furthermore most, if not all, religions started as a cult with a charismatic leader who was considered crazy at the time (and may still be considered crazy):
Moses - Judaism
Jesus - Christianity
Mohammed - Islam
Bhudda - Bhuddism
Joseph Smith - Mormonism
