However, I'm worried what might happen to Dogecoin in the future, since it has been quite some time that no new version of the QT wallet has been mentioned, neither some innovation to keep it going for the long term.
It would become ideal for Dogecoin to add SegWit to its code, and gain traction if it gains acceptance from the miners. Then, if it manages to become the first cryptocurrency to accept the scalable solution, it could rise in popularity once more (not to mention that transaction will be near instantaneous).
Nevertheless, Dogecoin is a great cryptocurrency being inexpensive and relatively stable, making it a great way to tip others or send micropayments faster than BTC at a fraction of the cost.
Looking forward to your opinion.
I believe dogecoin has a future. It is one of the best altcoins of these days. It has a capability to rise better than any coins so we just have to trust it. It is worth holding specially for miners around us who has this coin so we just have to know everything about it.
