Now, what is the exchange where I can sell these waves tokens called "bitcoin" for real bitcoin?
These tokens called 'bitcoin' are worthless.
They are not related to bitcoin at all. Someone just named a senseless token 'bitcoin'. Probably to scam other people.
no, it's not worthless. WBTC is the real asset/token which represents bitcoin on waves platform
in fact, we can make deposit of US$, EURO, BTC, LTC, ETH and more through official waves gateway
in return we receive appropriate token representing such coin/currency on waves platform
we just need to be careful because there are some fake assets with similar name
@ridertiger on waves wallet dashboard, if it's the real WBTC you will see the amount on your BTC balance
there is a minimum amount if you want to withdraw to your bitcoin address, something like 0.01
BTC I think
