agree. bitcoin would be better if we function it as an investment or asset because the price is not stable. we can get profit there.
but for me, I prefer my money in fiat and bitcoin, so I can buy things using my fiat and invest money using bitcoin.
It is going to be better if it not just being used as an investment but as a currency for its whole adoption in the whole world.
And we don't have choice today as bitcoin has not been yet totally adopted by the all nation, so we will still stick in the usage of cash.
But let's see in the future, if people using bitcoins are going to be a lot then it might make bitcoin considered as our new cash.
