On the topic of earning and growing a small amount of bitcoin, instead of Xapo you should consider FreeBitco.in. We're now offering 4% annual interest on ALL deposits and we pay the interest daily so it can compound for you.
Get interest on your faucet balance, gambling balance, or make a deposit from another wallet (that's what I've don). The offer is one of a kind, you should check it out...link below.
Darn, thanks for being a second set of eyes trying to find that. And yes, I have funds over at freebitco.in since you began the interest offering. That's both very kind and helpful.
Freebitco.in is just a faucet, yes they pay a bit more better than other faucets but that doesn't add up. If you have a lot of free times, search in google for "faucet rotator" and start claiming different faucets, it's a good start for beginners. Faucethub.io should be a better start for you to start building some low income everyday, 0.001 btc daily is quite possible there and if you really have lots of free time, you can win more daily. Check it out.
I am in no way affiliated with them, but I have only seen they are working well. I do not do faucets myself.
Did you read the rest of this thread? Just popping in on this comment is misleading. I'm actually earning several USD pennies or 5,000 to 10,000 satoshi every day doing the list of faucets I have currently. I have a day job away from this venture, so I can't spend all day doing faucets, that's one reason I'm looking for any potential suggestions for steps two and three of my original post.
5000 to 10000 satoshi is nothing. However since you are looking for some serious growing, now it is the best time I guide you to mine some alt coins. If you have a medium to good PC with a good processor, quad core of intel core i processors of 4th generation and up , and if you have a good graphic card, RX 470 or GTX 1050 ti and up you can make some residual income monthly from this mining.
Check here for guides on how to do it, it is simple.

If you don't want to do the setup and don't have time, you can download these softwares that will automatically mine the best alt coin for you. Just make sure you disable your antivirus as most of the time these are treated like false positive.
