Best mining options?

Just to know, another believer here. Recently mounted a 6x3080TI rig on RVN (315 MH/s) which ends giving fairly 300 coins a day. With price drops, profit is still there but lower (here the bills are quite high, around 350 per month). However I'm still believing in RVN, the project, the halvening and that it will increase. I wish for it, 'cause I've invested 12K in the rig and currently the break even has flown to more than 2 years (if selling with current price) 🙁 Any advise on switching some GPU power to ETH? I can withstand the power bills (at least by now) but I dont know if sticking all the mining power to RVN is the smartest option Furthermore, I'm willing to increase the rig but has to convince the family, any advise / good argument?

Thanks!
