You don't have to watch any chart when you are into bitcoin investment for long term. Anyone telling you to watch the chart is not giving you the right advise. All you have to do is keep buying your bitcoin from exchanges and withdraw to your non custodian wallet, it can be there for as many years as you want. Any strategy you decide to use is up to you the most important thing is that you are buying your bitcoin. But since you are in for the long term it would be more preferable to just use the DCA and stop stressing yourself trying to be awake at night to catch whatever price level you are targeting. It's fine that the auto buy worked for you last night when price got to the region you targeted, but what of other days when you won't be that lucky does it mean you will keep prolonging to execute your buy order? No wonder you are always awake at night to watch it. Bitcoin investment shouldn't be done in a manner that it will be like a burden to us. So my advice is this, you should buy at whatever price you meet bitcoin when your money is readily available, and avoid the stress of watching charts and keeping late night.
well I have a bitcoin ticker that I keep an eye on during the day, and when I see a decent dip I used to buy, but now I just auto-buy whatever the price is high or low, it was just nice to catch a low last night that I would have missed if I did the old way.
I`ll still buy extra during dips, but I won`t worry about it if I miss a few, I have a reasonable sized bag at the moment that I`m happy with, so the pressure`s off now and my laddering-in days are over now, it`s just auto-DCA for me

Their is a saying that goes like this, that the best time to buy was in the past, and another best time to buy is today, so my guy, it doesn't matter the current price of Bitcoin right now, what is very much important is that you keeps on buying just to increase the stash of Bitcoin in your possession, though you might decide to buy aggressively if you encountered a dip, if you have the financial leverage to do so, but that doesn't change the fact that the DCA accumulating strategy is the best way to acquire Bitcoin, because due to the fact that you are buying daily, weekly or monthly, you might even buy the lowest part of the dip that someone using lump sum method might miss because he thought that the price of Bitcoin will dip further.
So it's best to keep on buying, because we are still in the early daily of Bitcoin, so buying it regardless of the current price is the best way to go about it, because I am quite positive that in the nearest future, the value of Bitcoin will be 5x to 10x of it current price.
