I've been trying really hard to get referrals for the Cash Alarm app, not just for me, but because Cash Alarm's referral program pays equally in both directions, so any referral of mine is going to get 25% of my 200 coins every five minutes basically nonstop. I have one phone running a game from Cash Alarm 24/7 and have hit the cap on coins per five minute cycle. Now, I suppose you're here for the proof, so here it is: 
According to the app, payment can take up to 7 business days, but I got mine within an hour. Unfortunately, it seems to be limited to certain countries and does suffer some unfortunate KYC crap, but if that isn't too off-putting for you, click here to download Cash Alarm and start capitalizing on easy money. By the way, it took me about 10 days to hit the $20 withdraw mark, but a lot of that was at less than 200 coins per cycle. If I am diligent and don't let my phone sleep, I can hit the mark in a single 24-hour period now. That's $600 per month for just letting a game run, and you could be getting 25% ($150) of that plus your own earnings!
The reason I push Cash Alarm so much is because it is an excellent, free earning platform to launch an investment campaign into crypto from. Get your withdrawals to PayPal, push the cash to your preferred bank account or prepaid debit card, then go buy yourself some sweet, decentralized economic freedom!
