Are you pertaining to the current state of the blockchain network? I don't think it's so slow nowadays.
Funny how people call this the currency of the future. It's more like a bottle from hell!
Bitcoin believer no more?
If it costs more then it will lose its competitive advantage with other forms of remittance such as bank, paypal, ...
The advantage is still there which there will be no 3rd parties involved for each individuals transaction.
