LeuPay is fine c. 10-50k a month, occasional proof of transfers, invoices etc. for larger business transactions you send beforehand the expected amount, invoice etc, should be no problems, PaySera is also fine for larger sums. Issue is that people need to understand why do EMI exist, its for small stuff, digital transactions, little fees etc, thats how a EMI makes the money, with little staff and little costs.
People coming here and throwing millions of $ around and want a solution outside of mainstream Banking, and are ready to use these shady unsecure EMI's, just shows that the risk they are ready to take︀ with their money only proves that their money mostly is not earned on legal ways,︁ which is fine, but EMIs have their rules too and operate under licenses granted by︂ same authorities who oversee proper high street Banks, EMIs are not a street corner fruit︃ seller, and the FBME disaster that i still going on for years, made all countries︄ tighten up rules for normal Banks, let alone Online EMI Banks.
