Within each section, right now, the exponents remain the same. I’ll concede that when that’s true, the choice of notation is irrelevant.
However, occasionally, prices will straddle a boundary between 1.9eX and 9.0eY with |X - Y| = 1. In those cases, the different exponents will be easier to miss than the different number of digits or different number of leading 0s.
Check http://cryptomarketplot.com/accessible-index.html : the numbers are also aligned, and in less space that it would take if 5.744e-5 was to have all its leading zeroes.
