Good crypto trading *simulator*?

I have plans for how to use my crypto if it becomes profitable enough subjectively speaking for me to sell during this bull run. But selling is never the end of course and I plan to buy back in at a fortuitous time after that. Maybe try my hands at day trading.

I want to practice until it is time for all these things to happen though - so does anyone know of any good crypto trading simulator apps out there? Preferably as close to Coinbase as possible, as that's what I use right now, and as simple as possible. ????

Preferably also one where you can set your starting fund amount yourself - tried one where you start with $100K. I was like...dude, no. This is not useful - at this point I'd just cash out and invest in a business.

Anywho, thank you!
