Bitcoin is very slow transaction and fee is rediculus then why people bother buying it or considering it. I have £130 of bitcoin and I want to move it and it is asking for £28 network fee. Why should people bother having it. I can't wait to get rid of it when the fee is low.
Actually bitcoin is not useless as you think. bitcoin has been used as a popular payment currency in the dark world since the early year of btc.
For now, we need to make bitcoin used by everyone in the world as a global currency. But as long as the btc value not stable, it will very hard to become a popular currency in the world.
