You can also do the faucets and trade the shitcoins for btc but it'll take a while to get to 50000 sats. I've dumped my DOGE there because the transaction fee is low for DOGE and I'm collecting interest now. I'm also sending the BTC that I'm mining with the cryptotab browser so I don't have to pay any fees. Plus I've found some external shitcoin faucets that I'm dumping there like beancash, TRBO and Syscoin.
