The biggest risk of using Bitcoin is it's price. It's price is unpredictable anyone can't guess the future price of bitcoin it will lose or dump you can lose and earn from it but it is risky.
No if you just look at the value you will forget the real meaning of bitcoin.
The risk and also the unique feature of bitcoin is that it is "no regulation", Decentralization makes bitcoin invincible to exploitable weaknesses beyond psychology and panic from users.
Bitcoin is more than just a decentralized coin, it is the symbol of all crypto and the first poof of a decentralized ledger based on the blockchain technology. It's limited supply of only 21M is what makes it valuable and the fact that so many miners, investors and supporters are devoted to its growth. Additionally, BTC is become the new 'gold standard' and naturally it's getting more and more attention as the digital alternative to asset preservation.
In other words, BTC is proof that people want decentralization and that the concept works better than the norm.
