myfriendcrypto, if this is about micro-earnings, then it would be logical to use micro-wallets that allow users to accumulate their rewards in one place and to avoid dust transactions. That way you can send 10 satoshi (no fee) without any problems - but of course you can always set a withdrawal threshold. I don't want to promote the micro wallets that are currently popular - but if you're interested, let me know on PM.

Can you explain to me how the referral program works, because all I see is that by invite a friend you can earn $5 a week?
