How and why would the end of bitcoin (and any other cryptocurrency) occur? Value decrease? Legality issues? Different technology/ideas to supersede it?
If people stop using bitcoin, bitcoin will be dead. We see it in many altcoins. Some new altcoins are rising in price when demanded. Later, when people stop using it they dead.
Apart from this, the bitcoin system will always be.
yeah if bitcoin users stop to using bitcoin then it will be dead but its impossible because a lot of people are using bitcoin and altcoin will be never rise than bitcoin because there is a lot of services are available on bitcoin.
That's about right because we the people are bitcoin, nobody owns the technology and we the users and miners control it, no governments involved and that is how is was designed for use from the start.
But we must also use it as an everyday currency as much as we can i think, the more the word get out there then the more retails will be willing to accept it, online shops especially are always want to offer their customers the latest thing before their competitors.
There are some problems for daily shopping. Especially the process of confirmation time is a problem. This problem can be corrected by entering high fee values. But it takes a while for people to change their habits.
Beyond that, we can advertise bitcoin through our social media accounts. The more people have knowledge of bitcoin, the more they become used.
