Sounds silly honestly. Leeea may have a good point about the gift cards, though I myself don't know much about them, there was a Simpsons episode recently where Grandpa Simpson got scammed, where a bunch of people were scamming in a call center and being paid in gift cards LOL.
Honestly, mining for the crypto directly makes so much more sense...and no I didn't watch the video. Holding your own private keys is always preferable, even if you are going to mostly just sell for fiat. For instance, I am quite skeptical of nicehash, (sorry Larry) so mining directly on ETH or another coin to a good pool and then paid out to a wallet is the best. That said, I tried mining Raptoreum on zergpool for ETH, where they have an autoexchange. I am not sure about the effiency of it yet, due to fees, exchange, possible delays, etc...but the pool at least reminds me of the adorable Zerg race. I love zerglings.
