The Austrian financial regulator FMA has warned the public against Centauri Coin and CTX Line.
The CTX Line presentation says that Centauri is the second mostly accepted cryptocurrency after Bitcoin. But it is not true.
CTX Line also says that when you buy Centauri Coin, you will be paid an interest rate for holding the coin, up to 298% per year. So it is very probably just a PONZI scheme.
Moreover by accepting deposits from the public with the aim to provide returns, CTX Line is an investment service that is not regulated. This is why the Austrian FMA has warned against it.
