Hello,
Is it allowed to have 2 wallet with same email addresses ?
I think yes . But not sure .
About one year ago ,Actually I created blockchain wallet three times through single email I'd . And when tried the whole three one by one all that was working very well .
But here it depends upon you that for which wallet you want to make multiple Bitcoin wallet .
If you want to make two wallets in coinbase then you can't do .
But if you will make blockchain then their are much chances that you can create .
But here I will suggest to male unlimited address and wallet in myscellium wallet .
In mysscelium you can create new new Bitcoin adress and also can import and export private key with backup , All these can be dime by you without any use of I'd ( no mobile number , no.mail I'd , no certificate )
