I have 4.6 bitcoins, but I don't know if that's a good investment.
I want to know how much people invest in bitcoins, is it more then 10 bitcoins?
And what is the standard bitcoin investment?
I don't want to waste too much money on bitcoin, you know I'm not that rich and I have to pay bills.
OP, to be honest your money is good enough for investment but to be honest again, investment in some other way is too much risky, so just hold your coin and wait until it grows by itself and earn the profit. If you have skill and knowledge only then you can go for trading or gambling, otherwise only keeping the money save in wallet is the best option for the newbie. Do not fall for any trap or attractive scheme.
