I believed that bitcoin will not last because of government policy is against bitcoin and many people is seeing bitcoin as a scam, so with such points I don't think bitcoin will stay till 2030, and if bitcoin stay till then that means it will stay till further notice.
Please am not here to criticised cryptocurrency but from the attacks government attacks crypto I think such will come in reality.
It is uncertain and it remains like that forever. It wasn't the infinity life I saw in Bitcoin but I believe that it still able to stay in the market for many years. I don't worried about being controlled by the government or they ban this because they do this already in the past years but it is still fine and perhaps, Bitcoin is growing more and more. This simply means that no one could able to stop Bitcoin unless people had no longer use this.
In my opinion, bitcoin will still be here in the year 2030. Somehow, the adoption is just starting to grow stronger. So in 9 years to come, I believe, bitcoin will still be here. And the companies/institutions joining this market will further increase. But definitely, we can't tell if this will be forever. As nothing lasts forever. But in the next decade, I believe the existence of crypto or bitcoin will still be here.
