Where can such quantity be gotten ?
If you don't know what a crypto exchange is, then you have no business here at all
I recommend Pay NaMaidani - pay.namaidani.com. You will need time to fund your account to buy cryptocurrency. There is a limit of 100,000 per exchange transaction, then multiple transactions are required. You can exchange online in seconds. You will need more time to replenish the balance in the network.
This is funny because your website is a clone of so many other similar exchanges. Who in their right mind would really trust your service?
Are these also your websites?
1. pibuysell.com
2. paymaker.co
3. exoronchain.com
4. shirlynpay.com
5. neobank.pmhfintech.com
When you type something to write, at least consider that all the sites you listed do not exchange cryptocurrency for fiat. There are several million WordPress sites out there, but that doesn't mean they're all owned by the same person. Therefore, having common sense, it is worth understanding this.
I would like a legal business that is registered in a European country and pays taxes, has all the permits for such activities, to not merge with the nonsense you wrote, who will believe you with mockery. Yes, this is not such a popular service, because we have just launched it and are developing it, but we also have our own clients that we serve.
