I've known Laura (the CEO) for a while. She's a lawyer, and handles business smoothly.
They sit between you and the real estate seller and handle any/all crypto-related compliance on your behalf. This is what you are paying for. They handle all of the compliance so you will pass CIMA's intrusive AML checks.
AML is very strict here and we can thank Hollywood and their "hidden money in an offshore Cayman Islands bank account" nonsense they have been propagating for decades.
The banks here WILL NOT touch crypto and will bounce/refuse wires from all known foreign exchanges. Parallel is licensed under the VASP Act here and the banks do not bounce or freeze their wires because they know that proper due-diligence is being done.
Any more questions?
