Actually, I do trading for earning bitcoin and I think it is the best way of earning.Trading gave me good profit in short time.I used to buy some altcoin like LTC,DOGE,ETH in low price and sell when price goes up.Also I am earning decent amount by signature campaign.I don't try gambling because my luck don't support me.
Yup these are perfect option to make bitcoin in forum and online services. I think we need better experience to handle the trading initially and all would be fine to make bitcoin you have got a trusted network involves in the bitcoin trading site you are involved. Signature campaign decent way to make to an income but to get accept by the campaign manager until manage your post quality.
