If I have N200,000 today, what is the smartest way to invest it in Nigeria?

I will divide the money into 4, that is #50k each. The 1st #50k, will be invested in treasury bills, 2nd in a worthy etf, 3rd in mutual funds and the 4th in some promising stocks. Or I could use #50k for treasury bills, #50k into money market ( something to fall back on) and the balance #100k for trading in shares and stocks or etfs to take profits when the prices raise to 10% to 20% in value.
