If the price of Bitcoin can really reach 100K, then i can only say that i can't afford it, i would forget about btc and use my limited funds to invest in the altcoin.
I'm sure that bitcoin at some point is going to reach that price but it's not going to be soon, what you need to do is to think about how much bitcoin you can buy for now and for how much you can sell it in the future, if you do that you will realize that buying bitcoin right now is probably one of the best business that you are ever going to make, in fact if you buy enough of it you could change your life forever.
I will buy none because of the too high price. I want that the price of bitcoin should be normal so that everyone who wants to invest his money in bitcoin is able to buy some bitcoin or even satoshi. If the price reaches to $10k it would be enough for bitcoin. People who give such prices assume bitcoin as only business, but it is not only business but also a usable currency.
