Is the service and profitability, even if bitcoin is highly volatile, are the only two reasons why bitcoin is attractive to investors? Any good opinions or answers? Thanks
There are 2 main reasons for why people invest in BTC, well at least in my opinion.
The better, more selfless reason is that they believe in its decentralized ideas and might not fully like a centralized system that most of our financial systems have so far, and they like what blockchain technology is doing to our society and therefore are investing.
The other reason is purely money-based and they just get the idea from friends or media outlets that BTC will constantly go up as a currency, and in a year they can make thousands of the coin - I think this is the more popular reason nowadays.
