In my view, the investment should be according to our comfort levels. I work with FreshForex broker, as with them any investment is awesome for me. They provide 101% Tradable Deposit Bonus and that helps in gigantic way for me. The best part about it is that one  can be fearless due to no restrictions.

I think it depends on you how much money you can invest but if you are new trader then you should start with small amount of money and after some experience you can invest more money.

It should really depend on our ability as if we are good enough then we should be fine with higher investment, but if we are just starting up then our preference should be demo or at least minimum investment. I am in medium level and that’s where I give higher priority to FreshForex broker, where I get 101% Tradable Deposit Bonus, so even lower investment turns out bigger under their look up.
