Quite a few years ago I registered to circle.com (back then it was different company, there was no USDC) and they gave out 10$ in #bitcoin for signup.
I was thinking of creating multiple accounts. But I was lazy and didn't want to go through the hassle.
If I had dedicated two days back then to creating dummy accounts, I'd be most likely somewhere else today. On a yacht or something.
I think that in 10 years time every single of these zaps will feel like 10$ signing bonus.
Use them wisely...
