Why not invest to Bitcoin?

What is the chance of Bitcoin doubling its price? It currently hovers and doesnt have any large increasing price. And do you think someone will pay up to 20K for something, when he can have better alternatives?

Buy other cryptocurrencies which are not so popular but have the potential to be! And tell it to everyone that you bought it so they get interested! And this is the way how the price of you alternative cryptocurrency will rise dramatically and you can earn money!
