since you are saying that you can afford to lose it, i say put it in bitcoin. but if you are getting profit from your stocks(savings) at the moment i say you don't take all your money out of it and leave some be that way.
I was going to suggest the classic line of don't invest what you can't afford to lose - and I'm sure it has already been suggested - but it's true. Personally I wouldn't put all your savings in bitcoin but invest an amount you are comfortable with. I think in the long run bitcoin will be a good investment with great returns but remember nothing is guranteed.
Nothing is guaranteed but this is a good move to invest your savings into bitcoins and If you have a patience to hold it for next 5 years without using it then I believe you can expect great return on investment in the future and there are also many other advantages of holding bitcoins.
