Dogecoin is pump and dump coin by Elon Musk and I suggest select valuable coin that Dogecoin.
Why not BNB ETH DOT MATIC and LTC I think these are coin that may last for long race than those you mentioned earlier.
the answer is very easy because Dogecoin is decentralized really well,
especially when Doge was still at a low price and ELon Musk bought it and what happened was Doge experienced a spike in Holders,
one of their biggest holders was Elon Musk, this is why Doge is a coin that is very popular with everybody, when Elon tweets it then Doge goes up.
but does doge have any use cases in the project, i also don't know but for someone like elon musk, it's huge.and he can make doge look good and the usage maybe can be combined with his company.example pay something with dogecoin.
