Eventually in the future, bitcoin will be replaced by another crypto currency but not soon. Bitcoin will be available till 2023 for mining. After that bitcoin will remain the costliest crypto currency. However, those who have already set up their expensive mining system, what will they do?
They will obviously find another crypto currency to mine and that crypto currency will become the next big thing after bitcoin. Everything in life, has a expiry date and bitcoin is no exception. But that is not going to happen anytime soon.
Yeah, In real life everything has an expiry date and bitcoin does not have exception on that. Bitcoin supply is very limited and year after years the supply are being lessen by the investors and the miners, so after at least 4-5 years we will experience some changes on bitcoin because those who will get benefits in bitcoin for long term are those investors and miners who invested a lot of money. After 10 years bitcoin will face its best enemy and the miners might transfer to another cryptocurrency because of the volume of users,money and other kind of small issues that can cause for them to not earn a decent amount.
