I don't think anyone will be misled when they read or hear DCA because if you understand the meaning then you should know if you are to apply it or not, or whether it is convenient for you to apply at a particular time or not. Nobody is forced to DCA, the investor should know how much he has left to put into his Bitcoin investment just like he also calculate how much to invest in physical investment.
Bitcoin is Bitcoin, and DCA is DCA strategy. You can get profit or lose your money by interacting with Bitcoin through investment, trading, speculation but it's your responsibility. You decide your profit or loss, not Bitcoin.
DCA is just a DCA strategy that can be used by everyone, but will it bring profit or loss, similarly to Bitcoin, it depends on you. How you manage your capital, apply DCA strategy, will decide your DCA result.
You can get profit or loss with Bitcoin and DCA strategy, but it's your personal matter of how you do it and you're responsible for result.
