The question is, how does that apply to an exponentially increasing stock like bitcoin?
Since when is bitcoin a stock? And since when does bitcoin only increase?
It's more that there are not many stocks with a growth rate like BTC, so (if you're NOT new to bitcoin), is it really a good idea to use DCA and stagger your buys over a relatively long timeframe when you see that growth is starting to pick up?
Yes, if you are a good trader and can reliably predict the market you can beat DCA. But with DCA there is less risk of making a bad buy. With Bitcoin newbies bad buys often lead to bad sells, which is why I make the suggestion. I've made no claim it is optimal for all people, but if you have to ask (hence this thread), you probably want something simple without excessive risk.
