2-3 blogs will be very difficult at the beginning. It only makes sense if all blogs are loaded with enough power. so technically strategically seen, because you want to be visible with all three blogs.

I have been asking myself exactly this question for 8 days now. and my answer to me is: now that's just the right one, so at the beginning. my blog is also a kind of mixed goods store. and then it's sharpened (maybe).

presumably we ask ourselves the wrong question, because maybe the right question is: "do you write what YOU love?" if so, then it CAN only be right.

And the mix: Crypto + Personally is represented here frequently AND successfully. If you can do a lot of crypto, do that, it will bring you much more visibility than my themes. as a reader I want to see who writes it, because it is about trust in this bits and byte world. ergo: Crypto + Personally. I don't see any problem.
