One think I don’t like about the safecoin is the binary division.

With this division you have the following numbers:

0.5

0.25

0.125

0.0625

0,03125

0.015625

0.0078125

0.00390625

… until 2^248 divisions

But in the real world you use decimal number X.X, X.XX, X.XXX,… so if you need to made a transfer with decimals probably you need to divide your safecoin a lot of times only to reach the exact number generating a lot of new safecoin files.

Of course the binary division is easy in the computer wold but I think we can save a lot of space generating decimal division. We can divide the 248 bits in 62 4bit groups using only the 10 first position of each group and generate safecoin of decimal value (0.1, 0.01, 0.001…). In this case you need only 10 files to made a 0.X transfer and 20 files to made a 0.XX transfer saving a lot of space and simplifying the safecoin world.
