Never heard of that before so if you're into that kind of transaction better not use an unknown website or wallet provider. The option that I can tell you is to create a simple test run for bounty hunters by just asking their ETH addresses to send them a giveaway token. Take note to them that it's just a test run because you're still in trial phase. But this shouldn't work if you want the control for those addresses.
Download coinomi wallet on play store and create a wallet, write down your recovery phrase and keep privately, you an create multiple ETH address on coinomi, that website is not safe
IIRC, Coinomi only uses one Eth address per account? CMIIW.
