ln my opinion, $20k for dogecoin just in 5 years is quite impossible.
well, i also believe that dogecoin can last long, i already invested my money in dogecoin too, but i think in 5 years the price of dogecoin at least can hit $400 realistically.
we can only wait and see
If you thought the DOGE price would reach $400 in 5 years, you are unlikely to have a clue about the cryptocurrency market at all.
Do you know how much the DOGE capitalization would be if the price increased to $400

There are 131,800,000,000 DOGE on market * $400 = $52,720,000,000,000
Do you really think it is possible for DOGE's market capitalization to hit this level EVER?
