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.
