If Any service, with a High amount, Do not ask for documents or KYC info, Stay away from them.
Any regulated Institute in this world, Do not accept your High amount without KYC.
For your safety Also, You have to provide Your KYC.
If someone hacked your account and Claimed to be him?
What Happen then?
No Regulated service/broker/bank/financial institute, will accept 100k without a Source of Fund.
Thanks
