Buy the Dip and Hodl, that's the only way. Someone who saw it at 98.5k would think it will fall further as even the media predicted further fall before returning above 100k.
I know you are saying to buy the dip and hold is the only way because of the name of this thread, but do not be deceived by the name of this thread. Buying the dip is not the only way to achieve success in bitcoin investment, and since the name of this thread is to buy the dip and hold, you shouldn't focus only on buying the dip because it will delay you from starting up your bitcoin investment since nobody is certain if the dip will happen today or tomorrow. Since you are a lower coiner, you should focus more on accumulating bitcoin with the DCA strategy so that you would be at an advantage of consistently accumulating bitcoin anytime your money is readily available, which will allow you to accumulate more bitcoin than someone who is using the buying the dip strategy.
Especially for a newbie, planning an investment by buying dips will not be a good plan. Waiting for the dip while inexperienced and newbie will only make you lose buying opportunities. An experienced investor will stay out of this discussion, because he knows when to do what and what action will be right for him. But buying dips for a newbie is just a reason for delay. I never advise a newbie to buy dips, because this advice will only keep a newbie away from investing and maybe he will be deprived of investment.
When you are new or inexperienced in investing, I will advise you to invest in the DCA strategy. DCA gives you the opportunity to invest without any delay and allows you to enter at all moments of the market. You do not have to be experienced or wait for the right time to invest in this method. There is no specific time to invest in DCA, whenever you have investable money, you can buy and hold it for a long time. To buy a dip, you have to watch the market and wait for it to buy, which is a waste of time.
Waiting to buy Bitcoin at the dip is not a good decision for anyone that want to make good investment in Bitcoin because it's not certain that the price will reduce to the minimum expected value that you targeting before you will buy and this can make someone to loose a good opportunity buying Bitcoin at a good rate if you consider DCA.
I think buying Bitcoin by DCA is more preferable to waiting to buy in dip because with DCA you can be monitoring the price and still be investing on a particulate rate over the time and even if the price happen to appreciate instead of dipping as you are expecting you are already in business that will give you a good return which you can add up with the valuable capital to buy more Bitcoin by DCA.
