what is logarithmic price scales

[cafter]

many times researching about crypto and watching charts there is an option of like logarithmic scale or linear scale ,
and logarithmic regression band, etc logarithmics.
can you please tell me what is that
and what is difference between simple and logarithmic

To expand on what ETFbitcoin already said: Logarithmic scales make it easier to evaluate growth in terms of percentage.

A steady growth of, e.g. +10% a year, looks like a straight line on a log scale but hyperbolic exponential on a linear scale. If you look at a short time frame this may be barely noticeable, but if you look at decades of data (or deal with a much higher yield, as is the case with Bitcoin) the log scale will remain readable while the linear scale would just seem to curve into infinity.

Growth that reaches a singularity at a finite point.

When talking about Bitcoin, this seems about right to me 

No, but you're right though of course. Thanks for pointing it out, fixed it in my post above!
