I still can not understand why would we be the ones who should pay for token transfers? I never pay to get tokens during bounty. It seems to me that you are largely paid thanks to the workers on your site so that you can transfer us for free and easily on our addresses erc 20. Beginning 2019 what will happen? Are you overcharging us to sell tokens directly through your site? It is clear that as long as you do not transfer free tokens earned on our wallets, I go on strike!
Yes, in a classical airdrop model all the transaction are being carried by the sender. We have already described, why we are going away from it, in our article:
https://bountyhunters.io/blog/26Moreover, to send tokens to let say 3000 users cost about 3000k to our clients. We are working to optimize payments scheme. This way you have two options now - leave tokens on escrow smart contract (still available in your dashboard but not in your wallet) you can consider this the same way like then you are having some funds on centralized exchange.
Then you have an option to claim you tokens to you wallet, the same way like you have withdraw option on exchange, when you are making withdrawn on exchange you pay withdrawn fee, when you are making claim here you are sending a transaction and paying the transfer tx fee, to send a transaction you need a wallet, you are creating a new one, or providing you current keystore data to use it to sign the transaction. All operations take place on a client side (same way like MyEtherwallet does for example). We never transfer your keystore data anywhere, you can easily check this using network scanner.
Next version we will support Trezor/Ledger wallets to sign the claim TXs and MetaMask. We are working hard to make user experience as mach flexible and secure as possible.
