MMM didn't last even a year. Bitcoin lasts for 10 years and will not see the end in the foreseeable future.

I haven’t seen such a scam as it is in the crypt for a long time. Especially carefully you need to choose the exchange where you will transfer your crypto and withdraw from it too. It is better to read https://feedback-people.com/chernyj-spisok/kriptobirzhi the blacklist of crypto exchanges before choosing something. Otherwise, you can easily lose your finances.
