It's a relatively new currency, with several advantages in relation to fiat currency,
as fast and safe transactions, so I consider a good investment.
We can't actually rely just based on its advantages over fiat.
They are not enough of a factor to be said as a good investment.
And if we compare the advantages then I think fiat will be holding upper hand on bitcoins at a moment as fiat is more popular and almost all are using it and also it is widely accepted as a mode of payment.
