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.
I don't think so, BTC or Cryptocurrency as a whole manage to hold for more than a decade and still growing until now. Maybe the government will try to adapt the cashless payment system which will affect the economy of BTC in the near future but it wont be enough to take down BTC for a lifetime.
Bitcoin will last I think as long as the internet would last. I might have said before that it might last a few thousand years before, but now I might change that and tell my opinion that Bitcoin will last as long as the internet will. In case there is no internet then these hard drives that might have the blockchain might be the reservoirs of the coins and the whole process can be resuscitated once another civilization or maybe species decided to recreate the internet again in the far distant future.
