It seems that many misunderstand exactly what money laundering
or Ponzi schemes are. They have specific meanings, & aren't just
an insult or expletive for any financial impropriety.
1) Money laundering is taking profit from an illegitimate source,
eg, meth sales, & pretending the money came from a legitimate
source like a car wash. This converts unexplained money into
cromulent wealth. Then the crook fully launders the lucre by
paying income tax on it. (Remember how they got Al Capone?)
Squeaky clean!
2) A Ponzi scheme is using money from new investors to pay
old investors. When the crook has insufficient new investors,
the scheme collapses. Thank you, Mr Ponzi.
Trump's plan is to create something of value (an NFT), & sell it.
This is entirely legitimate....although the actual value is dubious.
