Bitcoin is first of all digital currency and on top of that decentralized. Many however consider and say that bitcoin is digital gold. If we compare gold and bitcoin in some way there are some differences but also they are unique, every in his own way. Only downfall can be trading them, both have solid gains but many are now in bitcoin more cuz of the high price.
Gold has now no impact in the investment list because people are not going for it every person who have resources he is buying bitcoin because he knows well that bitcoin will bring more wealthy days for him and the decentralized behavior of bitcoin has given trillions to the people and they are expecting more many of rich people are investing into bitcoin because bitcoin will give them much more to count in future.
