Yes you are correct, but what you wrote, like for example reason number one, it has good thing as well. Sure, bitcoin is easily affected, even a bit bad news can decrease the price. However, the same happened with good news, it can increase bitcoin price as well. That's why i guess you just need to wait for the price to increase, since it's volatile too so it's not that hard for the price to budge. Then, why should you worry about bank? Bank can't do anything to your bitcoin, and from my experience, i never get my money confiscated or something just because i earned it from bitcoin, it's not something illegal. But if in your country it's illegal, you might need to think other way. And lastly, yes. Unfortunately bitcoin is not common yet to be used in a transaction, but then it's why bitcoin is great for investment, since you can't use it anyway, just put it for long hold it and then gain profits from it. No need to spend it for purchase.

The thing is, all of the instruments in investing are risky, even though the risks have been set as low, there are still chances and reasons that would make you go broke.

And if that's the case, then why not go with the high-risk high-reward game instead? It would be the same anyway.

I never regret that I am currently in this community and support Bitcoin since then. And the investment I had before is now growing and rewarding me so I will agree with this.

It is the basic reason for Bitcoin.
However, I personally have some reasons why I must hold bitcoin right now:
- Want to get more profits
- The price of BTC is still down and I have no choice besides holding
- Waiting for the price of BTC can reach at least $80k 
More specifically

Basically it is from the characteristics of bitcoin itself that it can provide many benefits, there are many positive things that can be taken from its advantages, such as investing, of course. Other than that this has indeed proven to be of interest to many investors, there is no doubt about it because of the many offers from many investors.

Bitcoin is just similar gold which the supply is limited, and the circulating supply will increase only from mining that need long time and high energy cost. But fiat is very easy to increase the supply, only by printing for a second. If we compare Gold and BTC, BTC has more advantages because we can use it for cross border payment and take a few minute to comfirm, but for physical Gold hard to do.  The price action of BTC and GOLD is bit similar so in the future BTC possible to reach current marketcap of Gold, that is above $10T. For afew years BTC and Gold is against inflation of fiat.

Investing in bitcoin, because I love the technology it's used to, and everyone is currently learning for it, I believe it will be a bright future, it makes me always want to invest in bitcoin.

The main reason I invest in bitcoin is for profit or to double my money. I don't want to be hypocritical but it's true.
trading with high bitcoin price fluctuations will provide many advantages. But not just trading. I do the analysis first before I enter and exit the market.
Bitcoin or cryptocurrencies are great for short-term or long-term investments. Bitcoin is the most popular digital asset today.

Reason 01: For the Spreading FAKE news through any person or organization, Bitcoin can devalue BUT it is huge powerful fundamental community that has no big impact. Bitcoin has no regulatory body so no Government can interfere in it's activities for that's reason you haven't worry to Invest in Bitcoin.

Reason 03: Why you not Purchase your needed products from many stores at Once? If ALL the Stores Accept Bitcoin.

For sure I also ask myself why people would think that banks would close their account for no good reason. The only reason why banks will close your account is when you’re involved in illegal practices. If you’re the keep–your–hands–clean type of person, then you wouldn’t have anything to worry about banks closing your account. So you’re right about that particular one. And secondly , there isn’t many stores where you can spend Bitcoin, I don’t have any problem because I think the main purpose is just peer to peer transactions.

There are companies that pays their workers with bitcoin these days. Then as for the transactions taking long, it’s not something that happens all the time. Finally, your first point shows you don’t understand it. Bitcoin has a time it goes up big like it did this year, and it after every four years when there is a halving, and after the prices goes up, it always comes down. So, I don’t think it’s all about whatever nonsense any influencer has to say or not, because without them saying it, the price will still go down.

I anyway don't think there are too many other people who claim they invest in Bitcoin for philanthropic reasons. That isn't the case because it wouldn't make sense in the first place. Bitcoin is not like a piece of art that somebody might really buy and pay a lot of money for just because he likes the picture. There maybe a few exceptions though who say that they wanted to own at least some Bitcoin just because it was a revolution that took place during their own times. Probably though they would buy one of these coins with a private key within them, a real collector item.
