I did absolutely nothing, it's all earnings from referrals that are surprisingly still active. It just means that faucets are still interesting to some people.
Ngl, that's impressive with the current BTC rates! You're definitely fortunate to have these people actively working on offers since solely PTC earnings are negligible these days.
Probably Cointiply is the best faucet platform nowadays, even better than freebitco.in. But besides these two alternatives, I guess there isn't anything else satisfactory to become an user anymore. Cointiply doesn't have intrusive pop-ups, neither put you under risk of infection through malwares. It's a good app, with many earnings opportunities, despite them paying pretty low sums of money.
In every cases, it's a good one for young people who are starting their journey in crypto universe right now, just like we did 10 years ago or so. They can earn in Cointiply by completing determined achievements in other games apps, by answering surveys, claiming from faucet (which is simple and fast to do), and seasonal events.
I know that because there is someone close to me who is an enthusiast of Cointiply.
