I often see the ads in advertising billboard. I usually go to a public park every other day, and the road will pass through a major intersection with large billboard. At one point, a billboard of cryptocurrency broker appeared every time I passed through that intersection. The particular broker also advertises into a convenience store (7-11), so I will be pretty much guarantee to see its ads every day.

Another broker dared to register the domain name "Join the Crypto Revolution" to promote its scheme. I wish we could have an enforceable rules on prohibition to market cryptocurrency to general public like Singapore did (see [1]). We did open for comments regarding this, but it has not been set in stone as cryptocurrency broker tried to game the rules.
