This is a theory of many crypto nay-sayers is that we will all lose our total investment in the long run.
Not fair to assume this, if you ask me, since there are already people who have turned their investment into returns of profit.
I think the fact that there are people who have already turned their investments into returns of profit does not necessarily support the idea that cryptocurrency is a good investment in the long run.
In ponzi schemes, the people who invested in the beginning also get to turn their investments into huge returns of profit, but they are still fraudulent schemes in the long run.
That said, crypto is
not a ponzi scheme,
these are the characteristics of a ponzi scheme:
A guaranteed promise of high returns with little risk
Consistent flow of returns regardless of market conditions
Investments that have not been registered with the Securities and Exchange Commission (SEC)
Investment strategies that are a secret or described as too complex
Clients not allowed to view official paperwork for their investment
Clients facing difficulties removing their money
Evidently, the characteristics do not fit crypto at all.
