Before proceeding to the consideration of projects for "mining" bitcoins without attachments, I would like to remind you that 1 Bitcoin is 100,000,000 Satoshi. Accordingly, in order to get 1 BTC it is necessary to devote one project (which would bring 10,000 satoshs per hour) ten thousand hours, which is equivalent to 461 days. Of course, this is accelerated by the fact that simultaneously you can receive crypto currency at once from many faucets.
That is, you will use the involved 5 best bitcoin faucets, that 1 BTC can be received in 93 days. Given the current rate of bitcoin, we get (at the time of writing this article 1 BTC = 1173 dollars) that a day you can earn $ 12.5 (taking into account the work with 5 projects at once). The time spent on captcha input is 20 seconds per project. I hope that such simple math for you will be enough to make out whether you need this occupation or not.
And the last thing I would add - register Bitcoin wallet you can on faucethub.io site. This is done very easily and does not require any investment.
