The entire crypto ecosystem is a ponzi
This is a terrible argument, and clickbait. Obvious enough to anyone who actually understands how bitcoin, or eth work, it does not fit the definition of a ponzi scheme. Most tech stocks fit the definition better. Just because a few centralized banks, (FTX, centralized crypto exchanges are banks) have failed, means nothing, since the original idea of cryptocurrency was to do away with centralized institutions like this.
