Bitcoin and if you ask me why i will answer that bitcoin is more flexible than gold and for begginer it's also better, so bitcoin is my choise.
Yeah and people who are already using bitcoin will surely invest their money into bitcoin at a moment as they are aware that bitcoin can make them rich in a short period of time.
If I have gold, I would choose gold. But I don't have and bitcoin I do have. So, I will choose bitcoin. And yes bitcoin is very easy, flexible to use. And it can transfer easily where ever you are here in the world.
