> This unofficial currency exchange <
With so many legit exchanges in the world, why would the unofficial ones exist?
1. Binance
2. Cex.io
etc.
I'm seriously confused which one you call official and which one you call unofficial exchanges. Who can determine which one is official or not anyway? Bitcoin can be traded anywhere, you can even make your own exchange if you want. It's the same as if you build your own electronic store.
Most of the exchange you hear of will run out of business in 5-10years time but Bitcointalk will still be around as far as bitcoin still has value that means the currency exchange board will still be around and forum member can use it to exchange their coins.
This is a bold prediction. Any reason for you to say this? Imo I can't see Binance go bankrupt.
