after china and Korea Ban bitcoin exchange
Are you think Japan now bitcoin world leader ?
Yes, And definitely,china has already lost them position as bitcoin leader to japan.On one side, japan has already legalized bitcoin and started to gain importance in bitcoin market.
So In the same way it has been seen that the Japanese really consider bitcoin and it will not take long to dominate the world market.
The Japanese are past masters at taking up-and-coming technologies and turning them into a successful global markets, and I don't think this will be any different with altcoin - they are open to new ideas and developments and they will, maybe not overtake China, but certainly give them a run for there money in the altcoin world.
