100k Is a number which is just too high. I am sure bitcoin hold a lot of potential and in time we will see the true value, but that will be something more in the range of 10k/20k instead of 100k.
100k means the cap would be higher then many countries total BBP.
Exactly its an unrealistic value to think of and I don't see bitcoin going that higher in coming years and many people would be satisfied even if it achieves the price of $10k in future and if it does then majority of users will start dumping their coins for sure to make huge profits.
Almost traders are greedy, they cannot keep their target and will change if the price of Bitcoin increases faster than past time. That is reason some traders always tell they are loser, because they do not keep their opinion when Bitcoin reaches their target.
