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.
In my opinion this depends on the majority of bitcoin users themselves, if everyone realizes that bitcoin is a form of modern technology that can create business opportunities or is trusted to facilitate transactions whenever and wherever we are, technology like this must get strong support from the community.
most importantly, we must be able to avoid misuse of bitcoin as a means of criminal action. I believe that if all that could be done, Bitcoin will last a long time and be accepted by most countries
