Bitcoin is recorded as the first and most well known crypto currency in the world.
You might be surprised but Bitcoin is not the first cryptocurrency, the first cryptocurrency was eCash, created by DigiCash in 1990 but Bitcoin is the first cryptocurrency that had the best start and managed to take over the financial world and move it to another level.
Decentralized Nature: This means that no single entity such as a government or bank has control over it,and this makes it resistant to corruption or interference by any centralized authorities.
Bitcoin is decentralized by nature but it's not resistant to corruption and it's not prone to centralized authorities. In theory, with lots of power and finances, it's possible to gain significant control on Bitcoin.
I don't know if Bitcoin lasts forever but it's definitely going to last a long time.
