Those that are waiting for a dip before starting are a joke of a Bitcoin investor because they might not even start their Bitcoin accumulation journey at all, because even when it dip, they will say that it may dip further so they will wait, and by doing so the price might start appreciating from there which will discourage them the more from buying, and that is procrastination setting in in disguise.
So it is never a good idea to be waiting for a dip before starting your Bitcoin investment, the best way to go about it in my own opinion is by buying anytime your discretionary income is available not minding the price, because in the nearest future, this current price will be like a steal, and it will be too cheap when we look back.
The truth is if a person mindset is long term bitcoin holding less 4 to 10 years or more there is no for the person to be waiting for the dip before her or she can get started with bitcoin. As for those guys who are waiting for bitcoin to dip before they can get started with bitcoin they are very unserious guys, bitcoin is a store of value with potential returns, so why wait for bitcoin to dip before you can start accumulating bitcoin and hold? bitcoin can be accumulated at any fucking time and hold for long term, less say 4 to 10 years or longer, that's if your discretionary is made available, waiting for bitcoin to dip before starting your bitcoin investment is just another way to delay your investment journey, or your might even end up not getting started at, all the name of waiting for bitcoin to dip before you can start accumulating and and hold.
