One betting dapp with a volume of 100 BTC a day will already create a huge demand. Now imagine 50 IoT dapps, 10 betting dapps, 30 social dapps, ... I'm sure the demand will be there. It will just take a few weeks/months to pick up. The dapps need to be coded first. Before that all is speculation.
I'm not following.. I saw the dapps we'll be capable to use the Bitcoin API, if so.. they can easily bypass Lisk as medium of exchange and use just BTC. Is this correct or dapps are forced use lisk as medium of exchange ?
