don't invest 100% of your money in 1 place
I suggest you to split your money in some place

maybe you can buy some stock or you can invest with other currency like ripple or stellar 

To invest it because you'l get interest on top of your savings as well

Make sure to choose a relatively low risk, safe investment though.

Anyways who the hell will put up all his eggs in one basket.

Investing requires proper planning. Dont just take all the risk. It's like entering a battlefield with no proper equipments.

Im doing the same my fiat project saving is 25 years project ,that i pay from my salary,at bitcoin i only use it now when i need to buy something and the fiat ends soo i purchase with bitcoin after convert it.But my project from 2016 is saving atleast 80% from my income at bitcoin,lending them into exchanges as poloniex,soo making my coing grow slow but generating new satoshis without risk.

Just not only interest in saving the bitcoin for invest for short term. Actually Very good and far better for a long term goal because According to satoshi's predication bitcoin doesn't scratch the ground also. So wait and save Invest wisely in future.

To invest in real estate needs a lot of capital. I would rather advice to start with some premium stocks or some obligations fund.
Start with the easy investments products and build your way up.

i don't know, the onyl good investment right now seems bitcoin some other altcoin in top 10, like ethereum and the usual gold, so there is not much to diversificate

betetr to focus on the best one, surely don't live your fiat money doing nothing(with bitcoin this rule is not true) because, you can only lose their value

We know that time is gold and money is time, better to invest with interest, after days goes by the money that you're going to saved will goes back to you.

Saving money is good, anyway better than spending on things you don't need but only on long term, and it is good when you got in a moment of need for extra cash but investing for me is the real thing. Investing online now is so popular and you can really make good amount of money on not only gold, but on trading sites that are allowing to increase money if you are good. Investing money is having a risk itself of losing that money but who risk he won, that  it. I can only say that what more money you invest, that more you can get, you do not have to be scared or afraid of losing them because the more positive your toughs are the more money you can magnetize to get. Good luck

That is correct. And I have been doing this everyday to life a better life and have financial freedom. I only invest on assets or currencies that would survive in the long term (in this case Bitcoin). Later, I'm going to invest in Ripple, Stellar and Ethereum to serve a a long term investment towards the future.
