I have a similar story. In the initial months of 2020, I was having a tremendous good luck. I was able to turn 0.001 btc into 0.025 btc on a single mine game then it followed with dice till I reached 0.18 btc. I paid back all my small loans and dues. I withdrew it and spent around 0.05 btc on purchasing somethings I wanted like a smartwatch, a nice TV and some good hoodies. I thought I would be able to save the other funds as well. But soon I gambled the rest of the funds, betting as high as 0.04 btc on a single dice bet! I slowly and completely got empty and got back to getting small loans. I'm just glad atleast I spent some amount on things I loved 
I just imagine if I had saved that entire 0.18 btc, at today's btc price, I would have like $5000! But alas, what can we do! You said you won like 0.7 btc which is around $21,000! Truly a regret!
The way I see it, is, never let cash around you roam freely in your access, spend on something you love, eat good, buy important stuffs, go for vacation, the more you start to spend money and get joy, the more you will be cautious of busting out money which you can't afford to lose!
