Maybe when Bitcoin's market cap is the same as Gold's, then there would be enough gains to push Doge to hundreds of billions in market cap. But I think $5 would be a peak, and with the dump it would end up stabilizing at $1 or $2.
yeah, more likely the only plausible scenario for doge to go up that high is when crypto market cap is also growing so significantly which equates to flow of investment being abundant.
despite popularity, I think there are big chunk of investors who aren't exposed to crypto, therefore it's akin to untapped potential for crypto to grow.
with current rate, I expect that BTC nearing gold's market cap is possible. it's only matter of time, and once that reached, meme can just sweep in and join the train.
though I also think that it needs narrative as well for it to be hyped again.
