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.
Im pretty sure it wont last but it will leave something bigger ideas that comes from bitcoin to start a new one. Apparently all creations have ending that will start a new more innovative than the last.
