I run
Btcdiv.com, a site listing dividends to bitcoin holders in the form of altcoin forks and airdrop.
You've probably heard of Bitcoin Cash and Bitcoin Gold, but did you know there are over 50 other forks & airdrops available that you can (or will be able to) claim and then trade for more bitcoin? On Btcdiv.com you can enter your bitcoin address(es) and the site will search the address for the 10 most valuable airdrops.
Anyway, I would just like to announce that I've added an Exchanges section to the site. Finding a site where you can trade your free alts for Bitcoin is often the hardest part and hopefully this section will make it easier. I will try to list all exchanges that trade with bitcoin forks & airdrops and exactly what altcoin they trade and if deposits are available.
The section is still in rather early stage but I think it's already pretty useful. Please try it out and let me know what you think:
