Nobody is saying that trading and at the same time investing in bitcoin is a total waste of time if you can handle both there is no problem with that, but come to think of it if you are trading at the sametime you are investing how can you apply the proper DCA strategy
Actually, If you can trade and invest, that is your personal matter. If you can focus on other things while maintaining DCA while investing on bitcoin, that is entirely your personal matter. But if you cannot maintain DCA while investing in Bitcoin due to focusing on other things, then your investment trend will not be right and you will not be able to control the balance. If you can maintain these, then it is good, but maintaining DCA is the most important thing for investing in Bitcoin, no matter what you do.
Trading and investing seems possible but if you consider how addictive trading is and how easy it is for some to slide into addiction in trading, you will simply encouraging anyone you love to remain with investing and holding. Do you know how dangerous addiction to trading is? If you slide into addiction, I bet you that you will not be able to hold Bitcoin even if you create different accounts and wallets for those different purposes. You will always replenish your trading account the moment the funds there is depleted because of that addiction and losing will start becoming less painful because you want to satisfy a burning urge.
I have examined different scenarios and come to the conclusion that investing and holding is the best for me because it gives me the opportunity to plan and implement without exposing my capital to too much risk. I'm not too rich so I don't have money to throw away to the market hence, the little I have, I manage it properly in a way that I can compound it into something significant in the years to come.
