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.
