I hope bitcoin is the mother of crypto currency, i have 5 year experience and on this 5 year i can say bitcoin is the number of currency for safe your invest money, Because it is not possible to scam, if some times bitcoin price was big dump so no problem jast wait 4-6 month again it is will be recover your loss. But other currency fast time moon, than 95% currency scammed, so it is not safe. Only bitcoin is real it is my opinion
