Dogecoin has got a strong and supportive community which will make it live for long term due to its quick transaction confirmation and low transaction fees. However, due to the lack of innovation and developments on the team, i doubt Dogecoin can make any huge price rise to the moon. Perhaps McAfee intends to create another FOMO due to his large influence.
I think yess it's an FOMO from McAfee to make a Dogecoin Pump, maybe he's getting paid to say that. Dogecoin is difficult to Pump because its very crazy supply so Dogecoin is suitable coin for transactions not for investment.
