No, ponzi means that proceeds from later investments pay returns to earlier investors, this is not what is happening with Bitcoin. It might be what's happening

No, ponzi means that proceeds from later investments pay returns to earlier investors, this is not what is happening with Bitcoin. It might be what's happening to tether (in a sense that they pay withdrawals out of recent deposits and rely on having more deposits that withdrawals). Bitcoin might be a bubble like tulips, but it's certainly not a ponzi scheme in any "classic sense."
