I appreciate the feedback.

A two dimensional table is something I will consider. However, Im not quite sure how it would layout as a 51x51 cell table would be massively wide or require multiple smaller tables . I'll look into it and experiment with it a bit and see how workable it is.

As far as 1 bitcoin versus 50 bitcoins, It would make my tables needlessly large and require several extra digits to each number. It will be something that is more workable in the future as bitcoins increase in value, reducing the need to use so many digits when working with a single bitcoin.They are also issued in blocks of 50 so to me it just seemed more natural. I tend to view 50 bitcoins as a single unit, especially now when they are worth less than one cent per bitcoin.
