If you don't already know this, there's a bunch of virtual/temporary card services out there that might work if you can pay for multiple months up front. In the US at least, visa has a prepaid debit card that works on most sites I've tried. Maybe Revolut's virtual cards are credit instead of debit, but I haven't tried them so not sure.

I might be willing to consider paying for it myself somehow if you don't find another option, but that'd get complicated

That could be helpful as well. I think I remember with Mediafire you can host up to 20GB files for like $10/month, which I might be willing to pay for if that would work.

Thanks for those existing links!! I appreciate the offer on the altcoins, but it's not pressing for me at the moment, so it might not be worth the effort currently

This is very helpful, thanks!!

If anyone has ideas for altcoins, I'd super appreciate it.

Hi everyone,

Question's in the title. I started working on a project where I have only partial addresses (bitcoin, eth, ada, etc), and I want to search various blockchains to get a list of possible addresses that I can then narrow down to try to find the actual one I'm interested in. On Etherscan for example, it will autocomplete once you enter enough beginning characters, but what if I only have the last few characters or some in the middle?

I believe I can download the entire blockchain and then search that way, but I'm not actually sure if that's true and if it is I'm hoping there's a way I can do the search without needing to do so.

Thanks for the help!
