The opportunity for bitcoin's price to reach $100k is very close and I believe that price target can be achieved in the middle of the year or after the halving occurs, but it is possible that it can be achieved before the halving too if for example the current correction occurs, because bitcoin has not experienced a significant correction after the market increase from the beginning last February, so make sure you wait for lower prices to start investing in your portfolio.
If it is to invest and want to increase the amount in our own portfolio, I don't think we need to wait for much lower prices on Bitcoin. Because the current Bitcoin price is still a fairly reasonable price for us to continue investing if our level of confidence in the $100K price is large enough. However, for now I am still quite happy with the small correction that has occurred in Bitcoin even though I still hope to see Bitcoin at a price of $75K to $80K in the near future because that is also quite feasible to hope for.
Yes, I would agree with you, our investment pattern should not just be one who often waits the price to drop very low before deciding to make an entry. Bitcoin is volatile, a person may not get the exact lower price at which he/she intends to purchase therefore missing opportunities that should have been suitable to buy.
Bitcoin at $68k currently should not be seen as a high price, we touched an ATH of $73k, so comparing we can attest to facts that we are experiencing market correction which is a DIP and could be the perfect opportunity to invest in Bitcoin, we can't measure how much lower the price might get but for real, every entry price is profitable as long it's about Bitcoin. When ever we are to get to $100k it's not much of my concern probably as the halving is yet to occur but it's a must that definitely will Bitcoin reach $100k as soon the bull run begins.
