To many people do that so we can assume that they are newbie in the scene but once they learn on how to deal with any technicalities then for sure that there would be more potential profit especially if you or they are eager to learn a lot from bitcoin.
Assume what !! newbie?? Apart from influencers(which we all know that they are no noobs) i don't think investors announces their investment status, probably you mean they bluff publicly to make people think they are newbie, no one cares if you are a newbie or not they only care about what you have to offer.
Then provably they would miss a lot of chances for continue waiting for certain things that didn't come on their side. Since they are doubting to buy then I guess they are not really ready face any consequences and maybe afraid to lose their money since that's everything they have. That's why its important to settle thing needed especially bring enough funds so there's no one can bother them for deciding to buy and they can execute their orders at any price they want and for sure with that they can see a more better result that doubting on current situation which provably can make them regret on not doing any action while the price of bitcoin is quiet reachable for them.
Yes they might miss a lot of chances because it's pretty hard to know when things will spike, instead, in Btc investors sees a down trend in market as an opportunity to buy more Btcs,as you can see from the title
Buy the DIP and HOLD , it means buying the down trend and keep on holding.
However from your statement
That's why its important to settle thing needed especially bring enough funds
it not necessary to bring enough fund at ounce probably you mean accumulating enough funds into investing in Btc, if an investor wants to invest and he/she dosn't have enough funds, then he/she could try the DCA method of investing into Btc as it has been said across this particular thread
