Free money for crypto you're already holding.
If you already hold crypto, OKX's X Drops Club is about as close to free money as it gets. You keep your coins where they are, opt into the drops, and OKX periodically airdrops tokens to holders.
When it launched, a few stablecoins counted toward the holding requirement. OKX has slowly stripped those out, so it's leaner than it used to be. But if you're a long-term holder anyway, opting in still costs you nothing.
My own numbers: over five months, I've earned $4,090 for keeping about $20k of BTC in my OKX account and opting into the drops. The earlier drops were richer, but $1,586 of that has come since March 2, so it hasn't dried up.
There are two tiers. The standard tier covers $10k to $20k in holdings. The VIP tier covers $100k to $200k.
The catch, such as it is: your rewards ride on tokens whose value moves, and OKX can keep trimming what qualifies, the way it did with the stablecoins. But for coins you were going to hold regardless, it's found money.
