I'm not sure how I wound up in this thread, but what the heck, I'm here. I agree that volume means nothing more than a lot of people are 'mining' a specific coin or that a coin has a larger total coin supply. I've also seen your various posts about dogecoin, et al. I'm not sure I see the point really. I've also seen your posts refer to dogecoin as ponzi schemes or that they don't have real value, etc. which is humorous because the 'real world' says the same thing about bitcoin. From a technical nature, these coins are all basically the same with some changes in parameters and a pseudo name. How any one coin is somehow inherently more valuable than another is purely determined by the value that the community places on a coin. There is a community behind Dogecoin, so it took off... There was a community behind bitcoin and litecoin, so those took off. There is no community behind things such as mooncoin, so it doesn't do well. The development community also helps for things to take off. Dogecoin does have a number of wallets, tipbots, etc. which has probably helped a bunch.
My only argument against your posts is that from a technical nature, all these "coins" are the same. It's likely you're right and they're all sh*tcoins... It's likely that bitcoin itself is a sh*tcoin, purely because it itself has a ponzi scheme nature and no physical backing and might get killed by banking developments in fiat currency. But it's also possible that bitcoin, or dogecoin, or something like ethereum will replace currency in the future.
What I do wonder every time I see people vehemently against a certain altcoin is if its purely financially motivated? We all assume, and rightly so, that banks have a huge hatred for bitcoin because it will hurt them financially. I also assume that cryptocurrency fans who are vehemently against other altcoins are that way because they are heavily financially vested in one particular coin and the possibility of another coin taking off could risk their profit motives. People who are not profit motivated and truly want a cryptocurrency to take off because of all the benefits they provide don't really care what coin takes off, they just want at least one to do well.
One final comment i have is wondering why it has to be one coin? There are a few hundred fiat currencies in the world. Some of them are crap, some of them are pretty good. The crap ones don't necessarily hurt the good ones. I'd only caution that we watch how hard we try to kill various cryptocurrencies and the arguments we use. We might come up with some great criticisms and use those to successfully kill altcoins... then the anti-cryptocurrency folks will use those same arguments to kill ALL cryptocurrencies, including bitcoin.
