It was indeed a very nice puzzle for anybody having a bit of knowledge about the "internals".
I mean that although indeed it's a Bitcoin forum, far too many don't know what base64 is and also far too many don't know what to do with a list of binary digits.
So my advice is to make also puzzles for those with no IT background, or at least tell that those without a bit of IT background may "have difficulties"
Still, it was a nice one
Yeah people who are not aware about say base64 encoding or decoding might face difficulty in solving this puzzle as you said who are not from IT background could have trouble solving these puzzles.Although i would say binary is more known to people as they have learnt that 0-1 is computer understandable low level language basically termed as binary but after steps might be confusing.I mean that although indeed it's a Bitcoin forum, far too many don't know what base64 is and also far too many don't know what to do with a list of binary digits.

But still members could feel it interesting to solve while making efforts to learn about new things through this also so nice efforts by the @OP to start something which is helpful in learning new things to newbies.So make such puzzles for them to engage them more.
