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!

Though you lost a bit but good thing is that before you had bought few things which you had desire and not lost everything. So good learning for you as well that with winnings you should become more careful as it’s easy to lose and losing is more quickly than winning. So, play for fun and not just to keep multiplying and as well clearing debt should be first thing which you did perfectly.
Sometimes we are so unrealistic, we only thought of winning and when we win we come back again and expect to win. Gambling does not work that way especially if you are playing dice, you only win by luck, anytime you'll run out of luck.
The approach that I'm doing is just play a small amount, set some target and if you win that amount already, time to stop, don't be greedy as that would kill our bankroll, no matter how lucky we are since there's no way every time we gamble we win.
