Trillion dollar marketcap?
I doubt that doge coin can reach it easily. it's possible when more whales will try to buy big stash of doge coin from the market. We are still too far from the trillion dollar mcap. Doge needs to perform at least 10 - 15 times from the current price.
I doubt we can see that even in the next year. I personally think that the inflation of doge coin will become the main problem for sure.
Unlimited supply will prevent it to happen.
