I hope it will resolve the problem of OTP code verification system.
In my experience with OTP, If we use a phone number that not many people use it, they will ignore it, and the OTP didn't send it back. This is different when I use Telkomsel (the biggest provider Indonesia phone number), the OTP is very quickly received on my phone.
I hope that they do not ask for personal data , to make a withdrawal must be with the same name , so far I have not tried to make a deposit via a crypto network is this the same system must withdraw to a local bank with the same name ?
If you are going to play (deposit and withdraw) with your local bank account, it is recommended that you register an account with your original name as what you have in your bank account.
Let me share my experience, I register an account but I do not use my original name because at that time I wanted to play with crypto only.
The fact is that I was able to deposit with bank transfer and other e-wallet services although my account is not registered with my real original name.
However I will not able to withdraw my money into my bank account because my registered name is not the same as my real name as what I have in my bank account.
As per my experience, I could deposit with bank transfer and I can withdraw with crypto.
This may be one of the advantages of BK8, but make sure you don't mind using it as a real name to avoid any problems in the future. we don't know if you make the biggest winning and they need your KYC when withdrawing, So if not urgent let use real name or not at all, deposit and withdraw with crypto only.
