Dogecoin is not a cryptotulip, it is a currency, it is the currency of the future, the one that will be used to exchange goods in the Solar System. and therefore needs new supply for new users. The advantage over others currencies is that it has a controlled inflation, nobody can create at will, it is defined and everyone knows it.
If someone wants to speculate with cryptotulips to sell it to another and earn dollars or euros they can choose any other, Bitcoin, Stellar, Shibas, Coinye, or whatever they want, there is thousands to choose from. But do not use dogecoin as a cryptotulip for gain fiat because it is not, it is a currency with a specific objective.
If you believe that dogecoin is the "future of currency" I have some magic beans to sell you. Doge has never been future of anything, the coder of it made it up in 2 hours (literally said it himself) and it was just for a joke, there is a centralization with too many of the coins owned by too little amount of people, it is not solving any problems, it is not improved upon anything else, it is uncapped and it has manipulation problems as we have seen.
All of which shows that dogecoin is just a coin that should have died long time ago, even if it is alive today that doesn't mean that it will continue down this path, as soon as Elon comes out and says he is no longer supporting doge that is going to be enough to destroy all of it. This is why I would advise you to not be falling for this dogecoin hype and try to act reasonably or you are going to lose all your money.
