There is no point making such a generic question, you could have made a poll with a few answer questions. 99% of the users of this forum barely know the basics of Bitcoin and they do so only in very generic terms, and in the outside world the situation is even worse. Somewhere about 99.9% of the people do not know anything about Bitcoin. They may have heard some terms that are used in this process such as mining and decentralization, they most certainly may have
heard of the name Bitcoin but that is not the same as knowing things about Bitcoin.
I appreciate that you trust Bitcoin very well.
Bitcoin is about removing trust, if you are "trusting Bitcoin" then you are doing it wrong.
However, we must be aware that Bitcoin is still a high risk investment. The price is volatile, it sometimes can skyrocket but it can freefall at any time.
No, it is not. Stop repeating things from the past that don't apply anymore. Bitcoin is widely regulated, established in many places and has very low volatility compared to the past. It is less volatile than many stock alternatives. It is time to stop repeating this as it is the equivalent of baseless FUD, even if it was accurate in the past -- that does not excuse it.
There is no secret that I know, generally bitcoin is a digital exchange tool as well as a coin used for high-value investments followed by advanced technology, namely blockchain, maybe there are some issues that I have heard such as bitcoin being used in dark transactions such as hacker sites, but that is the past, almost everyone in the world knows the existence of bitcoin as a high-value digital currency and it is not a secret.
Funny, not a single claim that you have written here is accurate.
