I just bought few times and the grand total is about 1.5BTC and i used to trade and i've earned few dollars too.
Wow that's a big amount for getting your first whole bitcoin, I wish that I can try to do it. But I need to accept the fact that I'm not able to get one of it because I don't have enough fiat for buying it. So, what I'm doing is just trying to get some collections of btc and also in trading.
If you know how to trade you will see that it is easier to make a few bucks on trading then in investing in ponzi's or scams.
You do have to be careful since these days trading coins seems to be very volatile, just like bitcoin.
