Unfortunately I haven't found many good threads about trading in this forum. Most of them look more like speculation and not real trading or market analysis, so I can't give you any links. I actually came from sports trading as well (at betfair, that stopped operating on my country as well, because they don't want to pay for a license), so I guess we have a similar path. I don't know if you usually traded pre-live or live. I preferred to trade live at tennis and soccer, and tried a few pre-live at horses, but I didn't enjoy this last won, because I was lacking market analysis at that time, and I was better at game analysis.

If you did the same thing as I did, I suggest you look for some real price analysis info, because they are quite valuable in my opinion for crypto trading, but keep in mind that the market is ruled by FUD news that generate panic, or really good news that generate FOMO, so I think there are a lot of similarities between sports trading (live) and crypto trading, where the news in crypto, make the market move like key events on sports (goals in soccer, or service breaks in tennis).
