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.
That is not the only way you can earn profits from BTC, but if you want to earn a big profit from BTC, buy dip and sell when the price is very high in the market, which is the only way you can achieve such massive profits from BTC because it will allow you not to sell in the low price until the high price occur before you can sell to earn massive profits.
If they are not financial buoyant, I guess waiting for the dip is the best option for such category of investors to buy BTC from the market because it will help them to buy plenty of BTC and hodl for the price of their desire to come before they can visit the market to earn profit. But if you want to use DCA to accumulate BTC, make sure you are financial buoyant because there is nothing that will make you sell your BTC in a short term than to continue to buy in the dip to accumulate BTC in your portfolio.
