Imagine a situation where you own a house and a piece of land it's built on. You estimated the value of the whole thing to be $500k. One day someone knocks on your door and offers you $2m all of a sudden. Will you sell or suspect they know more than you? Maybe there's an oil deposit underneath your house? Maybe there's geothermal energy source? Maybe an international company has plans to build a facility nearby and will need your land for whatever price?
I will give it a second thought because my land that actually worth $500k and someone is giving me 2 mil for that same land will create doubt in my mind too. Either that would be suspicious like either the person or the offer is legit or not. Besides this, I would have the same thought also, but to overcome this hurdle I would do my analysis and will search out to other resources I will have to find out why they are giving me so much money for my less expensive land.
Once I find the answer I might not sell them, for example, one of my cousins lives in a city area and the land in front of them is worth around 30 lac (local currency) but that whole area become industrialized even the industries are far away from that land, but the owner of the land judged the people who brought the deal of that land of 2 crores. Once the owner found out that there land was worth that much due to this reason they decided not to sell and the last time I checked it was of 4 crore.
Will you simply give it away once someone hands you $100k, or decide that it's cheap and they know more than they're willing to share?
I got your main concerns here and they are really so legit that we all should learn this, if everyone is saying BTC will reach or at the least, it will cross $100k then most of the people will make some booking at this price tag but if the people are saying it will touch $150k then people will do the same at that price, but the real ones know that it has more potential than 1$100k or $150k, so they will not sell their lands (BTC) and will wait for the right moment.
