What else a coin needs? In these days, just heavy promotions alone enough for success of a coin and I believe Elon Musk is already doing that in more perfect way. In future they may adopt any new algorithm and then may go for swapping or anything similar to that. So, as of now dogecoins got something which is not at all possible for any other coin. So, we can expect dogecoin to continue its rally toward $1 in short term and then $5 in long run.

I ready when dogecoin will be trading around $7 to $8 it may surpass bitcoin in coinmarketcap ranking, thanks to its massive circulating supply (right now dogecoin is having around 117 billion of circulating supply). So, when new people enters into this crypto space then definitely they will consider dogecoin as one of their investment options.
