I just signup and on the site says "Rewarded miles can be only used by the person itself and can be exchanged for TNC after KYC verification." so its totally have a KYC maybe to filter cheaters and to distribute TNC equally among participants.

Main purpose: A distractions from bitcoin, alts were created to steal your bitcoin (keep this in mind always lol). This coins/tokens are been created from thin air just like the fiat so you lose focus on what the ideology begin bitcoin is. The industry has been monetized, some might argue that the reason behind so many tokens is because they're different problem each were created to solve but don't be decieve as most of the problem this new project claim to solved can be solved using Bitcoin.

Before the so called defi tokens we already have bitcoin that's truly decentralized and not all the centralized project claiming to be defi. The reason we have so many tokens is basically as a result of greed (project developers looking for fame, monetary value and ego of been one of the pioneer of the cryptocurrency industry.

Quick research through the so called aits you'll notice most operate similarly so why then do we need them all instead of focusing that energy on one and makes it a success. 99% of the other cryptocurrency are worthless and only valuable through trading.

It is such a good idea of introducing Bitcoin to people that are unaware of its existence,  bet you can never force the awareness on them. You only get to inform those who are willing to learn it . Many people are still unaware of the existence of Bitcoin, some are ready to embrace its learning and advantages surrounding it while some are not interested in learning it. For those who are ready to know much better about it, it is better to introduce them to the basics, such as: its enormous advantages surrounding it, how to choose Bitcoin wisely at the favourable market price, how to keep our wallet safely and so on.

@wapinter sir..Why did you, before starting a bounty campaign, did not ask for payment for your bounty campaign payment(escrow) ... after the bounty was completed, then you can distribute it directly to your bounty participants ... sorry, most bounties nowadays always release the responsibility of paying bounties after completion or  their project was a success .. I'm sure you know the current bounty is mostly like that..delaying payments, avoiding payments and reducing the amount promised ..
