And why would these experts accept tokens for their services instead of money or more known cryptos like btc?
Experts will receive for their services the tokens of the AskBrains project, which they will later be able to exchange for the usual BTC or ETH. I don't think this will be a problem.
If you can make such an exchange, then there is no problem at all. It is good that the team will allow such exchanges.
that can be transferred to a bank card or converted to Bitcoin. I wrote this already 2 times!
