I was able to save a bitcoin app, I wanna say thank you because it's very nice, maybe I should share it to some of my friends and i've been collecting bitcoins but my app had a prob coz of the covid19, I hope it has resumed once again. I should try the new apps and can collect bitcoins as well. Bitcoin is a digital currency which you exchange to dollars because we don't use real currency in technology anymore, we use bitcoins as well.
