Personally I think right now is a great time to invest in Cryptocurrencies.
Like someone said already just having Bitcoin at the rate it is growing in value is an investment in itself. Put in a good exchanger like Blockchain, Coinbase, Kraken, Ipayyou, etc.. has its risks while you wait for it to grow on its own.
If you feel the need to grow it I would suggest you start doing research on all the other different currencies out there. Read read read and invest in their growth potential if you think they'll grow faster than Bitcoin. Determine how much you want to invest. 5% of your Bitcoin in each say..
Of course you best invest in currencies that can be turned into fiat easily or back into Bitcoin quickly. That's a risk too.
So don't be in a hurry but get going right away because cryptocurrencies are all at ground floor right now and when they are accepted in your country mainstream people (regular NASDAQ investors) will be flocking in and grabbing all the best deals!
And like the other guys here say, stay away from MLMs, high interest money offers, offshore deals, etc!!
If you are not yet familiar with Open Ledger get an account and watch

Watch out for the "bots" now though. They are making things a little crazy out there but driving the prices down which could be good for some currencies!
