Bitcoin Icon in iPhone Style

This is a Bitcoin icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,800 icons, all in the same style and quality.
There is a circle with the letter B inside of it. The letter B has four tiny rectangles (all equal size), two on top of it and two on the bottom of it. By having these rectangles attached to the letter B, the letter appears to look like the US dollar sign - - $.
