can earn Bitcoins in many ways, for example you can selling your services and goods for bitcoin, you can also try to trade some used altcoins..
not a good way to get bitcoin and you have to sell your goods? there are many other ways. like trading, signature campaign and hunting giveaway.
I think its a good way to earn money because
with services and selling goods you can make a lot more bitcoins than by just trading.
Plus the fact is also that signature campaigns are profitable but most of the times you will not gain a lot of bitcoins by them.
lol are you sure services and selling goods better than the trade? whether you are going to sell your goods to earn a lot bitcoin? of course not! but with trading you can get a lot of advantages.
