Bitcoin is the best option at present to invest. But I feel that if you are looking for long term investment then Gold and Stocks are also better options. Just Own it And Forget it Don't hesitate even if the prices are going down and stocks you can sell at any point of time when you think that you are earning a good profit out of it.
Investing in gold and bitcoin is always good, as the future of both seems to be very positive which can give us best returns on our investments.
Gold investment is very good it is long term investment and the price of it is rising yearly because of its preciousness and i think for years to come gold can be harder to find by miners and that can affect for its price. And in bitcoin investment you can do short term to earn because long tern might turn scam .
So i you have patience better to save it and wait for the price rise or you can do investment and make sure to be wise to avoid lose.
Bitcoin is what you can consider to be precious as every one knows that there will never be more than 21M Bitcoins.
That's what makes Bitcoin more than interesting for investors and people looking for a long term store of value.
