I will choose both bitcoin and gold investing both will definitely profitable. Bitcoin is fluctuating its price it dump and pump but for sure will gives an earning. Though in gold as the most known for anyone will gives also profit in the long run.
And I do not invest in gold. Its hard to buy. It is easier for me to buy some part of bitcoin. I can do it in just a few minutes using my smartphone. I like it. And how to buy gold I do not know.
Due bitcoin is crypto currency, peoples commonly buy bitcoin through internet (online).
If we talk about how to buy, probably bitcoin has one point plus of it. Because gold is the real stuff if you want to buy have to go to the store. Or you can also buy gold online and look for sites that legite.
But everyone can not compared bitcoin and gold only in one aspect (how to buy) there still many aspects that gold is better.
