to me the best option is to invest your money in bitcon, and there you can get double services, one is that your money will be too safe in bitcoin and the second is that you can really make a good profit just for holding your bitcoin, therefore the best option is to invest your money in bitcoin.
Investing in bitcoin is not safe and involves huge risk as we don't know where bitcoin will land in future and what price it would be holding so you should invest only that you can afford to loose.
But if you have no trouble making ends meet and even got some spare money at the end of the day, you would most certainly want to preserve its purchasing power. Putting the money in the bank is essentially equal to admitting that you have no other idea where to put it. On the other hand, the very definition of spare cash means that you can, in a sense, afford to lose it (at least, some part thereof), right?
Why not then venture into Bitcoin, after all?
