When you do faucet claims, get into airdrops, or simply mess with altcoins a lot, you often receive coins, that are either too cheap to be traded in an "ordinary" way, or are non-liquid, or just dead with no trading volumes, or even delisted from everywhere. Normally you would sit hodling those pieces of precious crap forever with no profit.

Fortunately, there's a way to turn such coin dust (not all of it, but at least some) into something more useful -- to have it at an exchange that has a "dust burn" or "automatic conversion" or similar you-name-it feature of swapping sh*t into a more decent coin (mostly, into the exchange's native token).

I know three such exchanges -- Binance, Bitmax, and Crex24.

Binance has a Convert to BNB feature: "You can convert balances with a valuation below 0.001 BTC to BNB once every 24 hours. It is not currently possible to convert delisted coins". There's also a small conversion fee in BNB. Binancecoin is very popular and has a lot of use cases.

I use this feature regularly to swap my ZEN earnings from Getzen faucet.

Bitmax (not Bitmex) has a One-Click BTMX Conversion: any account holdings can be swapped into BTMX (via BTC) once every 24 hours with a 6% service fee. Then BTMX coins can be traded at Bitmax or stacked for dividends.

I stake Bitmax Tokens and use BTMX conversion daily for everything I can transfer to Bitmax exchange.

Crex24 has a Coin Burn feature: some coins can be swapped into Crex token that can then be traded for BTC, USD, RUB, or EUR. The conversion rules are rather unclear, it seems the admins change them quite often playing with allowed coins, amounts and everything.

Anyway, at Crex24 I regularly swap my CRW earnings from Crowncoin faucet and even the nearly-dead CBTC coin and many other altcoins from Graviex faucets.

However, I would like to have more exchanges with the dust-burn feature. Please let me know in the comments if you know any.
