Waiting for a drop is never the right approach. This will make you miss out on buying. You think that if Bitcoin reaches $90,000, I will buy. If it doesn't, then you have missed out on buying. You can continue to buy consistently using the DCA method, so you can buy at all levels. If you want, you can set aside some money to buy aggressively.
If you are going to hodl long enough - you can buy anytime, and be in profit.
but for the time being now, we should expect more of the market pump and its more likely that we get to all time high this month or sooner.
In my own opinion paying attention to something like double bottom and double top, head and shoulder chart pattern or inverted head and shoulder chart pattern is pointless if you are a Bitcoin investor, it's only traders that pays attention to that, do not forget that 103k that the price of Bitcoin is currently now is actually a bargain in my own opinion in ten to twenty years time to come, so what's the point analyzing the market before buying?
Or have we forgotten so soon that 69k which was the previous all time high two years ago is now a bargain price, and that is how I am very much positive that this current price will look like in years to come.
If you are a trader, it would be very much understandable because you success and failures rely on that, but as a Bitcoin investor your duty is to just buy and hold, then what's going to secure your holdings on the longer run is by having an emergency funds in place so that you wouldn't have to temper with your holdings when in real life emergency situation.
