Who does that? You're buying a residential IP or just some type of service that offers that. VIP72 and 911.re are pretty good examples that offer real IP addresses from real people. Lots of fraud going on there, but at least you won't use
VPN IP addresses. PayPal doesn't like that at all. And depending on country it's easier or harder to setup a real business account. I'd say that anywhere in Europe it's quite easy. You just need some type of ID card + address +
bank account. PayPal just checks the address automatically. Sometimes they're asking for proof of address, but a bank statement or whatever is enough and easy to make. It's extremely easy. Depending on what you're selling it can hard to keep that going.
You're wrong. Normally banks just don't want the 'shady' funds from users on here. Nearly any traditional bank is happy to accept new customers, also for
crypto. Just avoid EMIs. They suck anyway and give no deposit guarantee or anything else that helps you keeping your funds.
