We are talking about bitcoin here.. not shitcoins. Hopefully, you and others are not considering that there is some kind of a similar value proposition to invest into shitcoins as compared with bitcoin.
Yet, I question the sentiment of your whole post, Negotiation. You seem to think that watching the BTC price matters in regards to when to get into bitcoin, yet if you have an investment timeline of 4-10 years or longer, and most likely it should be 10 years or longer, then why would there be any need to figure out if BTC happens to be in a dip or not?
I am not against the idea of buying when there is a dip, yet I see no reason to wait for any dip before getting started, especially since it could take 4-10 years or longer just to build a bitcoin position, unless you are able to front load your bitcoin investment - yet many folks are not able to front load their bitcoin investment, and they end up building their bitcoin position over time with ongoing, continuous, persistent, regular and perhaps even aggressive buying that is within their ongoing receipt of discretionary income.
It may not matter a whole hell of a lot if you buy the dip or not, especially if you might be receiving an income every week, and then there can be questions about the extent to which you hold back some of your discretionary income in order to wait for price dips that may or may not end up happening. Waiting for price dips likely puts a bitcoin investor in a wrong mentality, even though surely there could be some psychological pleasure that comes from holding back some value for dips... while recognizing and appreciating that the dips may or may not end up happening.
