This isn't specially wrong, but its just speculation, there is no real way to tell if BTC will reach those values, the one thing that we do not know is if other technologies will make BTC obsolete. The tech behind BTC was already outdated when it launched, aside from the ledger/blockchain innovation the code itself was already dated and now is a dinosaur. Chances of new tech making it obsolete and the price stop rising are greater than most people expect.
