If i understood correctly, you were having $60,000 and decided to open a sport betting & casino site? If i were you, i wouldn't think i would do that since you need much bigger than that amount to start a site, especially a casino. Then you said you paid $2000 for 3 times, that bring you have around $66,000.

My advice for you, just re-started from your bussiness on 2017 back then ,maybe with a new site since you have sold your both site.
