Funny to see YOU asking if something is unethical.
Nevertheless to answer your question there is nothing unethical to market a ponzi if you DO STATE that it's a ponzi.
A ponzi is very similar to some kind of gambling. If you enter early enough you can get a pretty impressive jackpot. If you don't you lose it all.
Problem is that 99% of Ponzis try to market themselves as honorable business with solid backup. They'll say they're experts in financial transactions, that they're miners looking for funds to expand... Whatever.
But if you clearly say "hey come join us in this ponzi, it's still early you'll get tons of money out of it" then how is that different from advertising for a casino which says "hey come bet your money you can win really big". In both cases you risk money knowing the only certain winner is the bank
And it is funny to see a legendary member talking like kids .

This seriously made me laugh
. You have no idea what you are talking about . This way I would rent my localbitcoins account for scams . I strongly condemn ponzi(s) . And I am sure any guy having common sense will not support it .
