You are very optimistic.
Honestly i don't think it's realistic at all. Any figure above 2k is just guessing like a child would do.
Any guessing between $200-2000 is just guessing like an idiot would do. No critical thinking at all. Okay, I'm exaggerating a bit. I think there's still a chance for bitcoin to be between 200-2000 in 2020; it isn't very far away. But that chance is not that high, maybe 20%.
It'll either have gone way lower, or way higher. The current price of bitcoin is because of its value as a speculative asset. That is literally 99% of its market cap right now. If nothing happens in another 4-5 years, the speculators will start losing hope, and get out, causing a crash in price. If something big happens, then there will be another huge hype cycle followed by another crash (probably). Those are the most logical choices.
The only reason you idiots think that it'll stay around the same as it does now, is because you *think* it isn't realistic for it to change by a lot; because "it can't be that easy to get rich."
There's no way you can get rich just by holding something for a few years, right?
RIGHT??? WRONG.
Masayoshi Son gained over 1000x return in alibaba in ~10 yrs. Property prices in many cities in China literally went up 100-200 times in the past 10 years. Same with Dubai. And there's google, facebook, uber... etc etc etc.
Venture Capitalists routinely make investments that return over 100x their investment. That's how their businesses work. They literally get that kind of return EVERY SINGLE YEAR (on some of their investments). Otherwise they'd go out of business.
So just because you think it's unrealistic, doesn't mean shit. It just means you're ignorant and stupid.
