Bitcoin Solitaire is an application made by Bling which gives you bitcoin that you can withdraw to your Coinbase wallet. Earning is not really fast but it's legit, you can play 10 matches a day which gives you 100k(by 1 match), more/less, in game coins, that you can convert to bitcoin. I will leave screenshot of convert rate points in BTC and i will leave screenshot of my BTC balance in € that i earned by the app (i just redlined my email address because i use it for too much things so i cannot show it lije it's nothing). Withdraws can take 48h sometimes, but, in my case, it was always shorter than 4h so don't worry if you don't get your payout instantly because there is only one developer behind the game so he cannot do it that fast, and that's why you can withdraw only once in 7 days.
