I love educated guesses

Unless this was for Beginners only? The title makes it look that way, but the rest of the topic doesn't look like it.
I've adjusted the title replacing "Beginner's giveaway" by "Educational giveaway", hope it's better now and people don't think it's for beginners only.

I consider the 1st block of 2020 will be the block number 610.770 (606.309 + 4461 = 610.770).
Added to my list.
Let's Hope for the best

Yess =)
Good luck!
