I advise using the DCA when purchasing Bitcoin or other cryptocurrencies; it's a great method to save money and ensures that your wallet never has a zero balance. Actually, most communities nowadays operate in this manner.
The strategy that's greatly appreciated by most of us and that's the reason why many are starting to do DCA. If no one does DCA then it's not recommended. But it's not just one person that recommends it but there are plenty of us.
Just be sure you know which cryptocurrency assets you plan to purchase in order to build up and create a dyor still, or select a cryptocurrency that you believe has the best chance of rising from the bull coins by selecting a majority of the top 30.
Start with BTC and then when you have sufficient holdings of it already, that's when you try to find something new.
