try to find altcoin faucets: http://www.dogefaucet.com, multifaucet.tk, http://www.free-crypto.com/ etc,...
send all the coins you can get to the same account and trade them for BTC
Why don't you mention Bitcoin faucets? That would be a much more direct way to earn bitcoin via faucets than using a doge faucet and converting. The faucets are going to pay the same equivalent amount in fiat across all alternative cryptos.
Also, you should put links to all the other threads on this board that cover the same topic, here's a few:
- https://bitcointalksearch.org/topic/best-way-to-earn-bitcoins-1006151
- https://bitcointalksearch.org/topic/how-do-you-earn-free-bitcoins-1139127
Is there a reason why you decided to start a new thread that discusses a topic that exists in at least two other threads on the first page of this board?
