Coin selection before investing in DCA investment method is very important for any investor. Now if we choose one of the worst coin to invest in and invest in that coin consistently for a long period of time, we will never get success from that investment. First of all we have to focus on coin selection, when we can select the right coin then we have to make sure which method we will invest in. For example, I first considered Bitcoin as an acceptable coin to invest in and then tried to consistently invest in this coin. I have maintained my investment for several years and will continue to do so in the future.
No one invests in Shitcoin, everyone trades with Shitcoin. DCA is not a useful method for trading. DCA brings to mind long-term Bitcoin investment, as Bitcoin is the only coin that is reliable for investment. You can't call Shitcoin reliable for investment. Because Shitcoins have less ability to recover value and cannot pump up the value like Bitcoin, many times Shitcoins are lost. No sane person would ever invest long term in such coins. Many trade with Shitcoins, I would advise them to be careful because trading in Shitcoins is also very risky. We know Bitcoin as investment and DCA as investment. In all types of investments we should be long term especially in DCA without long term you will not get good output.
