I'm trying to find answers and real experinces, not just opinions of "experts"
Alright, good luck with that and hopefully you find those opinions of people that have actual experience to have you satisfied. But just an idea from me, mostly, almost no one will go into that unfamiliar website that you've given. And having that percentage per month sounds too good to be true and highly likely a scam, that 13% APY is for real and legitimate if it's for a year. There, you have the idea, my friend.
