I do not know about you, but I sure easily would like to know how to spend some time on getting some Bitcoins for free, or almost free, or while I do something else I anyway needs to do one way or the other.
No one gives you money/Bitcoins for free.
Many links do not work so I think the goal of your post is to get the money out of the ads.
It is better to recommend wallets better than these BitCoinEra/ blockchains
I have gotten payouts from several of them already!
