I was skeptical about cryptocurrency as they seemed like a financial gimmick (Also because I'm a buffet disciple and he had different views on it) but not anymore. Not because I understand bitcoins or cryptocurrencies but I can sense the pattern where the fiat currency will be eliminated by this new format of what we call money.
Why is Bitcoin cheap around 50K?
The big companies are entering into the field and they don't think its too late to invest in it then why should we ?
There are already predictions of BTC crossing 200K in a couple of years. Aside from the speculation BTC has gained enough attention & momentum that it can't be stopped and if the money keeps being deployed into the currency out from the other asset classes then it'll be the next big thing.
The world is shifting towards technology based products. There will be a time where everything would be connected to the grid till then we can all speculate the rise and fall of the new normal.
Looking at where the technology and the world will be in the next 50 years or so "Bitcoin is Cheap".
